Novel drug therapy of acute hepatic failure induced in rats by a combination of tadalafil and Lepidium sativum.

BACKGROUND: Hepatocyte death and a systemic inflammatory response are the outcome of a complex chain of events mediated by numerous inflammatory cells and chemical mediators. The point of this study was to find out if tadalafil and/or Lepidium sativum (L. sativum) could help people who have been exposed to carbon tetrachloride (CCL4) and are experiencing acute moderate liver failure. This was especially true when the two were used together. METHOD AND MATERIALS: To cause mild liver failure 24 h before sacrifice, a single oral dosage of CCL4 (2.5 mL/kg b.w.) (50% in olive oil) was utilized. Furthermore, immunohistochemical expression of nuclear factor kappa B (NF-κB) as well as histological abnormalities were performed on liver tissue. RESULTS: The results showed that tadalafil and/or L. sativum, especially in combination, performed well to cure acute mild liver failure caused by CCL4. This was demonstrated by a decrease in NF-κB expression in the liver tissue and an improvement in organ damage markers observed in the blood and liver tissues. Furthermore, such therapy reduced interleukin1 beta (IL-1ß) and tumor necrosis factor-alpha (TNF-α) levels in the liver tissue. It's worth noting that the tested combination resulted in greater liver improvement. CONCLUSIONS: According to the findings, tadalafil and L. sativum, particularly in combination, have the ability to protect the liver from the negative effects of CCL4 exposure. Because of its capacity to improve liver function, restore redox equilibrium, and decrease inflammatory mediators, it is a prospective option for mitigating the negative effects of common environmental pollutants such as CCL4.

Selenium protects against nesfatin-1 modulation of the hypothalamic-pituitary-testicular axis during hypothyroidism in male rats.

Normal gonadal function can be disrupted by hypothyroidism. Hypothyroidism disturbs testicular function directly and centrally by affecting the hypothalamic-pituitary-testicular axis with unclear mechanism. As nesfatin-1 neurons co-localized with TRH and GnRH neurons in the hypothalamus, it could play a role in centrally hypothyroidism induced testicular dysfunction. Selenium (Se), by affecting thyroid iodide supply, could relieve these disturbances. So, we aim to identify the role of nesfatin-1 as a link between testicular dysfunction and hypothyroidism through modulating the MAPK/ERK pathway while discussing the possible role of Se in alleviating hypothyroidism and associated testicular damage. Forty male rats were divided equally into: Control: distilled water, Se: Se orally, Propylthiouracil (PTU): PTU orally, PTU + Se: Se with PTU orally. Serum thyroid function, gonadal hormones, nesfatin-1, testicular redox status, sperm analysis, brain tissue GnRH, nucleobindin 2-derived polypeptide, pMAPK/ERK gene expression, histological changes and immunohistochemical expression of testicular proliferating cell antigen (PCNA) were done. PTU induced hypothyroidism and reduction of gonadal hormones which both were correlated with reduced nesfatin-1. There was testicular stress with reduced GnRH, NUCB2, pMAPK/ERK gene expression, and PCNA immunopositive cells. These parameters were reversed by Se. Nesfatin-1 could be the central link between hypothyroidism and disturbances of the hypothalamic pituitary testicular axis.

Effects of ginger extract and/or propolis extract on immune system parameters of vaccinated broilers.

Newcastle disease (ND), avian influenza (AI, H5N8), and infectious bronchitis (IB) are important diseases in the poultry industry and cause significant losses. Vaccination is the most practical method for controlling infectious diseases. To reduce vaccination costs and several disorders in poultry farms, using herbal water supplements for immunomodulation with vaccination is critical to improving or preventing some conditions in the poultry industry. However, drinking water supplementation of ginger extract (GE)/propolis extract (PE) alone/in combination may increase broilers' humoral and cellular immunity due to the immunomodulatory effects of ginger and propolis. This protocol aimed to see how GE/PE alone or in combination improved the immunity, immune organ gene expression, and histology of the immune organs of broilers for 35 d after vaccination against NDV, H5N8, IBV, and IBDV. The chicks were dispensed into 5 groups according to GE and/or PE with vaccination. The control group was offered normal drinking water without any supplements or vaccinations. The GE group was supplemented with ginger extract (1 mL/L drinking water) in the drinking water before and after vaccination for 2 and 3 d, respectively. The GE+PE group was supplemented with GE (0.5 mL/L drinking water) and PE (0.5 mL/L drinking water) in the drinking water before and after vaccination for 2 and 3 d, respectively. The PE group was supplemented with propolis extract (1 mL/L drinking water) in the drinking water before and after vaccination for 2 and 3 d, respectively. The fifth group was the vaccinated untreated group. This experiment showed the immunomodulatory properties of GE and/or PE against 3 common diseases, NDV, AI, and IB, in broiler chicken farms for 35 d applied to a vaccination program. Thus, ginger extract and propolis extract supplementation in drinking water increased antibody titer, INF, IL10, and IL2 and TLR3 gene expression in the bursa of Fabricius, thymus, and spleen, respectively, as well as cellular immunity as indicated by increased CD3, CD4, and CD8 in the bursa of Fabricius, thymus, and spleen, respectively, with normal lymphocytes in the medulla of the bursa, thymus, and spleen. In conclusion, propolis extracts alone or with GE improved all of the metrics mentioned above without harming the histology of the immune organs.

Impact of vitamin D in children with chronic tonsillitis (immunohistochemical study of CD68 polarisation and proinflammatory cytokines estimation).

Inflammatory processes are increasingly attributed to macrophage polarization. Proinflammatory macrophages promote T helper (Th) 1 response, tissue repair, and Th2 responses. Detection of macrophages in tissue sections is facilitated by CD68. Our study is focused on the expression of CD68 and the estimation of proinflammatory cytokines in children's patients with chronic tonsillitis secondary to vitamin D supplementation. This hospital-based Randomized prospective case-control study was conducted on 80 children with chronic tonsillitis associated with vitamin D deficiency where (40 received vitamin D 50,000 IU weekly for 3-6 months and 40 received 5 ml distilled water as placebo). The serum 25-hydroxyvitamin D [25(OH)D] was measured using an Enzyme-linked immunosorbent assay on all included children. Different histological and immunohistochemical studies for the detection of CD68 were done. There was a significantly lower serum level of 25(OH)D in the placebo group versus the vitamin D group (P < 0.001). The levels of pro-inflammatory cytokines, TNFα, and IL-2 significantly increased in the placebo group as compared to the vitamin D group (P < 0.001). The increased level of IL-4 and IL-10 in the placebo group as compared to the vitamin D group was insignificant (P = 0.32, 0.82) respectively. Vitamin D supplementation alleviated the deleterious effect of chronic tonsillitis on the histological structure of the tonsil. Tonsillar tissues of the children in the control and vitamin D groups demonstrated a highly statistically significantly lower number of CD68 immunoexpressing cells compared with those in the placebo group (P < 0.001). Low vitamin D may play a role in chronic tonsillitis. Vitamin D supplementation could help reduce the occurrence of chronic tonsillitis in susceptible children.

Herb-Induced Liver Injury by Ayurvedic Medicine With Severe Lactic Acidosis: A Case Report.

Lactate is the basic blood parameter in the arsenal of an intensivist when managing a critically ill patient. A 62-year-old male presented with nausea and vomiting. He had been using an Ayurvedic medication, Insulin Management Expert (IME-9), for his type 2 diabetes mellitus and was found to have severe lactic acidosis that was resistant to initial fluid resuscitation and Ayurvedic medicine-induced liver injury. He required admission to critical care for organ support and ultimately recovered. Because current literature on the adverse effects of this Ayurvedic medication, particularly hepatotoxicity, is limited, causality was determined using the adverse drug association tool Roussel Uclaf Causality Assessment Method (RUCAM), which determined this as a probable cause with a strong score of seven. As a result, our case adds a vital gear to the wheel of current research literature.

Ameliorative effect of sesame oil on experimentally induced polycystic ovary syndrome: A cross-link between XBP-1/PPAR-1, regulatory proteins for lipogenesis/steroids.

Polycystic ovary syndrome (PCOS) is a mixed endocrine/metabolic/reproductive disorder in women of reproductive age. Sesame oil (SO) contains sesame lignans & vitamin E with broad-spectrum antioxidant and anti-inflammatory effects. This study investigates the ameliorative effect of SO on experimentally induced PCOS and elucidates the possible molecular mechanisms with a deeper focus on the different signaling pathways involved. The study was carried out on 28 nonpregnant female Wister albino rats that were divided into four equal groups; Group I (control group) received oral 0.5% wt/vol carboxymethyl cellulose daily. Group II (SO group): orally administered SO (2 mL/kg body wt./day) for 21 days. Group III (PCOS group) received letrozole daily, 1 mg/kg, for 21 days. Group IV (PCOS + SO group): concomitantly administered letrozole and SO for 21 days. The serum hormonal and metabolic panel and the homogenate ATF-1, StAR, MAPK, PKA, and PI3K levels of the ovarian tissue were calorimetrically evaluated. However, endoplasmic reticulum (ER) stress was evaluated by ovarian XBP1 and PPAR-γ messenger RNA expression level using the qRT-PCR technique. Ovarian COX-2 was detected immunohistochemically. The results suggest that SO-treated PCOS rats showed a significantly improved hormonal, metabolic panel, inflammatory, and ER stress status with concomitant decreases in ATF-1, StAR, MAPK, PKA, and PI3K in ovarian rats compared to the correspondent values in PCOS without treatment. CONCLUSIONS: The protective effects of SO against PCOS are triggered by ameliorating regulatory proteins of ER stress, lipogenesis, and steroidogenesis through the PI3K/PKA and MAPK/ERK2 signaling cascades. SIGNIFICANCE STATEMENT: Polycystic ovary syndrome (PCOS) is the most common mixed endocrine-metabolic dysfunction among women within the reproductive period, with an estimated prevalence of 5%-26% worldwide. Doctors traditionally recommend metformin for PCOS patients. However, metformin is known to be associated with significant adverse effects and contraindications. This work aimed at shedding light on the ameliorative effect of sesame oil (SO), natural polyunsaturated fatty acids-rich oil, on the induced PCOS model. SO proved to have a marvelous effect on the metabolic and endocrine derangements in the PCOS rat model. We hoped to provide a valuable alternative treatment for PCOS patients to avoid the side effects of metformin and to help PCOS patients for whom metformin is contraindicated.

Esculentoside A Inhibits Proliferation, Colony Formation, Migration, and Invasion of Human Colorectal Cancer Cells.

Esculentosides include a group of plant-derived compounds with tremendous pharmacological potential. The antiproliferative effects of esculentoside A against different colorectal cancer cells were evaluated. We found that the proliferation of all the colorectal cancer cells was halted by esculentoside A. The IC50 of esculentoside A ranged from 16 to 24 µM against different colorectal cancer cells. Investigation of the underlying molecular mechanism revealed that esculentoside A caused an increase in the colorectal cancer cells at the G1 phase of the cell cycle, indicative of G0/G1 cell cycle arrest. The percentage of G1 cells increased from 22.68% in control to 54.23% at 16 µM esculentoside A. We also found that the colony formation of HT-29 cells was inhibited by 59% at 24 µM esculentoside A. Finally, effects of esculentoside A on the motility of HT-29 colorectal cancer cells were investigated, and it was found that esculentoside A caused a significant decline in HT-29 colorectal cancer cell migration and invasion. The migration and invasion of esculentoside A-treated HT-29 cells were 45% and 51% higher, respectively, than those of untreated cells. Summing up, these results suggest that esculentoside A exhibits antiproliferative effects against human colorectal cancer cells.

Potential of Ascorbic Acid Supplements to Ameliorate the Deleterious Effects of Hyperuricemia on Albino Wistar Rats' Hippocampus (Structural and Functional Study).

INTRODUCTION: Diet rich in purines may increase the serum level of uric acid causing hyperuricemia, contributing to learning and memory to impairments. Ascorbic acid has a potent antioxidant potential. The hippocampus is a pivotal component of human brains and other vertebrates that plays crucial roles in the consolidation of information and spatial memory. Our study was mainly designated to examine the potential palliative role of ascorbic acid supplements on harmful effects induced hyperuricemia on the hippocampus of albino Wistar rats. METHODS: Forty rats were subgrouped into the control group, ascorbate-only group, hyperuricemic group, and combined hyperuricemia and ascorbate group. RESULTS: Ascorbic acid has strongly preserved the histological architecture and maintained the normal hippocampal functions in the hyperuricemic group. CONCLUSION: The anti-inflammatory and antioxidant properties of ascorbic acid could protect the hippocampus of albino Wistar rats against the hazardous impact of hyperuricemia.

Influence of insurance status on the postoperative outcomes of cytoreductive surgery and HIPEC.

BACKGROUND: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is increasingly performed for peritoneal surface malignancies but remains associated with significant morbidity. Scant research is available regarding the impact of insurance status on postoperative outcomes. METHODS: Patients undergoing CRS/HIPEC between 2000 and 2017 at 12 participating sites in the US HIPEC Collaborative were identified. Univariate and multivariate analyses were used to compare the baseline characteristics, operative variables, and postoperative outcomes of patients with government, private, or no insurance. RESULTS: Among 2268 patients, 699 (30.8%) had government insurance, 1453 (64.0%) had private, and 116 (5.1%) were uninsured. Patients with government insurance were older, more likely to be non-white, and comorbid (p < 0.05). Patients with government (OR: 2.25, CI: 1.50-3.36, p < 0.001) and private (OR: 1.69, CI: 1.15-2.49, p = 0.008) insurance had an increased risk of complications on univariate analysis. There was no independent relationship on multivariate analysis. An American Society of Anesthesiologists score of 3 or 4, peritoneal carcinomatosis index score >15, completeness of cytoreduction score >1, and nonhome discharge were factors independently associated with a postoperative complication. CONCLUSION: While there were differences in postoperative outcomes between the three insurance groups on univariate analysis, there was no independent association between insurance status and postoperative complications after CRS/HIPEC.

Efforts in Bioprospecting Research: A Survey of Novel Anticancer Phytochemicals Reported in the Last Decade.

Bioprospecting natural products to find prominent agents for medical application is an area of scientific endeavor that has produced many clinically used bioactive compounds, including anticancer agents. These compounds come from plants, microorganisms, and marine life. They are so-called secondary metabolites that are important for a species to survive in the hostile environment of its respective ecosystem. The kingdom of Plantae has been an important source of traditional medicine in the past and is also enormously used today as an exquisite reservoir for detecting novel bioactive compounds that are potent against hard-to-treat maladies such as cancer. Cancer therapies, especially chemotherapies, are fraught with many factors that are difficult to manage, such as drug resistance, adverse side effects, less selectivity, complexity, etc. Here, we report the results of an exploration of the databases of PubMed, Science Direct, and Google Scholar for bioactive anticancer phytochemicals published between 2010 and 2020. Our report is restricted to new compounds with strong-to-moderate bioactivity potential for which mass spectroscopic structural data are available. Each of the phytochemicals reported in this review was assigned to chemical classes with peculiar anticancer properties. In our survey, we found anticancer phytochemicals that are reported to have selective toxicity against cancer cells, to sensitize MDR cancer cells, and to have multitarget effects in several signaling pathways. Surprisingly, many of these compounds have limited follow-up studies. Detailed investigations into the synthesis of more functional derivatives, chemical genetics, and the clinical relevance of these compounds are required to achieve safer chemotherapy.

Impact of Different Storage Regimes on the Levels of Physicochemical Characteristics, Especially Free Acidity in Talh (Acacia gerrardii Benth.) Honey.

This study investigates how storage conditions (temperature and duration) may affect the physicochemical parameters, especially free acidity (FA), of Talh honey originating from Acacia gerrardii that have naturally high FA levels. Fresh Talh honey samples were kept at 0, 25, 35, and 45 °C, and analyzed monthly over a period of eight months. The Talh honey was monofloral with 69% A. gerrardii pollen content. The free acidity (FA) of freshly harvested Talh honey samples was higher (93 ± 0.3 meq/kg) than that of standard limits (≤50 meq/kg) and remained stable at 0 °C throughout the storage period. A significantly increase in FA started to occur after storage for 6 months at 25 °C (103 ± 0.2 meq/kg), 2 months at 35 °C (108 ± 0.3 meq/kg), and 1 month at 45 °C (112 ± 0.3 meq/kg). After 8 months of storage, the highest FA level was recorded at 45 °C (159 ± 0.5 meq/kg), followed by 127 ± 0.3 meq/kg at 35 °C, 105 ± 0.2 meq/kg at 25 °C, and 94 ± 0.3 meq/kg at 0 °C. It was found that 0 °C was an appropriate temperature for storing honey for long time. The electrical conductivity (EC) of fresh Talh samples (1.46 ± 0.0 mS/cm) was above the accepted limit (≤0.8 mS/cm), which was slightly increased (non-significant) throughout the storage period under all the storage temperatures. Hydroxymethylfurfural (HMF), diastase activity (DN), and reducing sugars (RSs) showed normal levels only at 0 °C and 25 °C throughout the storage period. However, HMF exceeded the standard limits after the first month at 45 °C (127 ± 9.6 mg/kg) and after the second month at 35 °C (90 ± 23.5 mg/kg), DA decreased below standard limits after the second month (5 ± 1 DN) under 45 °C and after the seventh month under 35 °C (7 ± 2 DN, and RSs decreased below 60% after 2 months under 45 °C and after 6 months at 35 °C. The physicochemical parameters (moisture content, pH, color, and sucrose) were the least affected and were within the standard range throughout the storage period under all the storage temperatures. The levels of FA and EC in fresh Talh samples were higher than the acceptable limits. The moisture content, pH, color, and sucrose content were not affected by storage conditions and remained within the acceptable limits. HMF, DA, and RSs were significantly affected by storage conditions only at 35 and 45 °C. The storage of honey at low temperatures (0 and 25 °C) for up to eight months presented the least amount of changes in the honey, and the honey was unchanged from its fresh status. Honey storage at 35 and 45 °C resulted in significant changes. It is recommended that Talh honey, which normally has high acidity levels, should be stored at temperatures not exceeding 25 °C.

The Impact of Rumen-Protected L-Arginine Oral Supplementation on Libido, Semen Quality, Reproductive Organ Biometry, and Serum Biochemical Parameters of Rams.

This study aimed to investigate the effect of oral supplementation of rumen-protected L-arginine on semen quality, testes, and accessory genital glands biometry in rams. Ten apparently healthy and fertile rams were randomly divided into two equal groups; control, and rumen-protected L-arginine (20 mg/Kg body weight for 30 days) treated group. In all rams, ultrasonographic measurements of the testes and the accessory genital glands and blood sampling were performed at day (D)10, D20, and D30 (D0 is the start of supplementation). Semen ejaculates were collected twice/week and semen quantity, and quality was examined. Our results showed that, in the L-arginine treated group, there were significant increase in the ultrasound biometric measurement of right seminal vesicle (RSV) and right Cowper's gland (RCG) at D10, both testes, tail of the epididymis (TE), SV, and CG of both sides at D20, and of both testes, RTE, RSV, RCG, and LSV at D30. Semen quality and quantity parameters were significantly improved in L-arginine treated group. Moreover, testosterone level in the L-arginine treated group was significantly higher than that in the Control group. Serum thyroxine and glutathione peroxidase concentrations were significantly higher in the L-arginine treated group. The present study concluded that oral supplementation with rumen-protected L-arginine is beneficial in improvement of rams' fertility.

Prognostic Interplay Between Coronary Artery Calcium Scoring and Cardiorespiratory FItness: The CAC-FIT Study.

OBJECTIVE: To assess the incremental prognostic role of coronary artery calcium score (CACS) and exercise capacity (EC), two independent prognostic tests in the assessment of patients with coronary artery disease. METHODS: The cohort consisted of patients who had clinically indicated exercise stress testing and CACS assessment from January 1, 2015, to September 30, 2021, with a median of 27 days between each other. Exercise capacity was defined by peak metabolic equivalents of task (METs) achieved during exercise stress test. The CACS was determined by the Agatston method. Patients were observed from the latest test date to incident major adverse cardiac events (inclusive of all-cause death, nonfatal myocardial infarction, late revascularization, and admission for heart failure). RESULTS: There were a` total of 1932 patients in the study population (mean age, 56±12 years; 42% female, 48% hypertension, 21% diabetes, 48% dyslipidemia). Peak METs below 6 was achieved in 8% of patients, and the median (interquartile range) CACS was 9 (0-203). In multivariable Cox regression models, both CACS (1 unit increase in log CACS: hazard ratio, 1.19; 95% CI, 1.06 to 1.34; P=.003;) and EC (1 unit increase in peak METs: hazard ratio, 0.89; 95% CI, 0.81 to 0.97; P=.01) were independently associated with outcomes. Using CACS+EC added incremental prognostic value over clinical and fitness models (C index increase from 0.68 to 0.75; P=.015). Incident event rates increased across categories of CACS and EC. CONCLUSION: Our analysis found that CACS and EC have complementary risk-stratifying roles in coronary artery disease.

In silico approaches to develop herbal acaricides against R. (Boophilus) Microplus and In vitro Anti-Tick activities of selected medicinal plants.

In tropical and sub-tropical areas of the world the most damaging pest of the livestock sector are cattle tick, Rhipicephalus microplus. The current study was aimed to generate phytochemical derived acaricides to control Rhipicephalus microplus populations, to maintain livestock herd production, minimize economic losses and to reduce uses of man-made chemicals acaricides. To achieve this goal, Adult immersion and larval package test were used to determine the feasibility of Berberium lyceum and Tamarixa aphylla against Rhipicephalus microplus ticks. Further, an In silico technique was employed to discover biologically active substances from both plants using docking method. Berberium lyceum and Tamarixa aphylla exhibited a reasonably high fatal effect at 40.0 mg/L on egg laying (index of egg laying = 0.19 and 0.19) respectively, thus inhibiting the oviposition (49.5 and 45.1, respectively) and the larval mortality (97% and 93%, respectively). Further, we also used Chem-Draw ultra-software (v. 12.0.2.1076. 2010) to illustrate different structures of38 known bioactive phytochemicals which are discovered in the PubChem database and verify the hypothesis that tick inhibition was linked to acetylcholinesterase (AChE). Barbamunine and rutin from Berberium lyceum showed remarkable interaction with RmAChE1 active site residues with docking scores of -9.11 to -8.71 while phytol and dehydrodigallic acid from Tamarix aphylla showed comparable docking scores of -7.17 and -7.14 respectively against Rhipicephalus microplus acetylcholinesterase protein. Based on obtained result, we believe that Berberium lyceum and Tamarixa aphylla bioactive components could be potential candidates in the control and management of Rhipicephalus microplus and should be studied further as a supplement or replacement for synthetic acaricides.

Evaluation of Venous-to-Arterial Carbon Dioxide Tension Difference as a Complementary Parameter During Pediatric Septic Shock Resuscitation: A Prospective Observational Study.

OBJECTIVES: The aim of this study was to evaluate the venous-to-arterial carbon dioxide tension difference during early resuscitation in pediatric septic shock. METHODS: A prospective observational study was conducted in the pediatric intensive care unit of a tertiary care teaching. Children having septic shock aged from 3 to 60 months were studied within the first 24 hours of admission. Central venous and peripheral arterial blood samples for blood gases analysis at time of central venous catheter insertion and after 6 hours were obtained. Central venous carbon dioxide pressure, arterial carbon dioxide pressure, and their difference (delta Pco2) were recorded. Patients were categorized, accordingly to delta Pco2 after 6 hours of resuscitation, into high delta Pco2 group (≥6 mm Hg) and low delta Pco2 group (<6 mm Hg). RESULTS: Oxygen extraction ratio at 6 hours of resuscitation was significantly lower among the low delta Pco2 group. Arterial lactate showed marked improvement in the low delta Pco2 group to be less than 2 mmol/L at 12 hours of resuscitation. Low delta Pco2 group showed significant higher shock reversal with shorter shock reversal time. Mortality was significantly lower among low delta Pco2 group with shorter pediatric intensive care unit stay. CONCLUSIONS: Delta Pco2 after 6 hours of resuscitation of <6 mm Hg indicates normalization of tissue perfusion during pediatric septic shock management. It could be used as a complementary tool to guide the resuscitation in the early phase of pediatric septic shock.

Cytoprotective Antioxidant, Anti-Inflammatory, and Antifibrotic Impact of Celery Seed Oil and Manuka Honey Against Cyclophosphamide-Induced Cystitis in Rabbits.

Patients treated with cyclophosphamide (CP) usually suffer from severe hemorrhagic cystitis (HC). Our previous study exhibited that mesna + celery cotherapy partially ameliorated HC. Therefore, there is a substantial need to seek alternative regimens to get complete protection against CP-induced HC. The current study investigated the effects of mesna + celery seed oil (MCSO) or mesna + manuka honey (MMH) cotherapy against CP-induced HC in adult male rabbits. The forty rabbits were divided into four equal groups and treated for three weeks. The control group (G1) received distilled water and the second group (G2) received CP (50 mg/kg/week). The third group (G3) received CP + MCSO (CPMCSO regimen), and the fourth group (G4) received CP + MMH (CPMMH regimen). The urinary bladder (UB) specimens were processed to evaluate UB changes through histopathological, immunohistochemical, ultrastructural, and biochemical investigations. In G2, CP provoked HC features (urothelial necrosis, ulceration, and sloughing), UB fibrosis, and TNF-α immunoexpression. Besides, CP reduced the activity of antioxidant enzymes (GPx1, SOD3, and CAT) and elevated the serum levels of NF-κB, TNF-α, IL-1B, and IL-6 cytokines in G2 rabbits. In contrast, the CPMMH regimen caused significant increments of UB protection against HC in G4 rabbits compared to the partial protection by the CPMCSO regimen in G3. Therefore, our study indicated for the first time that the novel CPMMH regimen resulted in complete UB protection against CP-induced HC via combined antioxidant, anti-inflammatory, and antifibrotic properties.

Molecular epidemiology of virulent E. coli among rural small scale dairy herds and shops: Efficacy of selected marine algal extracts and disinfectants.

Virulent pathotypes of E. coli seriously affect the livestock regarding the misuse of antibiotics. All 180 samples collected from cow's environment and dairy shops in Qena, Egypt were serologically and molecularly positive for coliforms. Enteropathogenic E. coli (EPEC), Shiga toxin-producing E. coli (STEC), Enteroinvasive E. coli (EIEC) and Enterotoxigenic E. coli (ETEC) pathotypes were isolated from water and milk-related samples. STEC serogroups O26, O55, O111, O113, O145 were also recovered. The non-O157 STEC serotypes were recovered from human diarrheagenic patients contacting cattle or consuming contaminated water/milk products. BlaCTX-M and blaTEM genes were detected in 25.5% and 100%, respectively. Disinfectants and algal extracts, identified by GC-MS, were evaluated in vitro for antibacterial activities. TH4+® disinfectant and methanol extract of Turbinaria decurrens reduced E. coli at 13 log10 at 1.5% and 3 mg/ml concentrations, respectively. Ag-NPs/T. decurrens showed 8-9 log10 reduction at concentration of 1.6 × 105 NPs/ml. Examined water sources, milk and milk products were potential reservoirs for virulent antibiotic-resistant E.coli which may impose animal and public health threats.Abbreviations: APEC: Avian pathogenic E. coli; blaCTX-M: ß-lactamase inhibitors-Cefotaximase gene; blaTEM: ß-lactamase inhibitors-Temoneira gene; CFU: Colony-forming unit; DAEC: Diffusely adherent E. coli; DEC: Diarrheagenic Escherichia coli; DEMSO: Dimethyl sulfoxide; eaeA: Intimin or E. coli attaching gene; EAEC: Enteroaggregative E. coli; EHEC: Enterohemorrhagic E. coli; EIEC: Enteroinvasive E. coli; EOSQC: Egyptian Organization for Standardization and Quality Control; EPEC: Enteropathogenic E. coli; ETEC: Enterotoxigenic E. coli; ExPEC: Extra-intestinal pathogenic E. coli; GC-MS: Gas chromatography-mass spectrometry technique; hly: Hemolysin gene; STEC: Shiga like producing E. coli; stx1: Shiga-toxin 1 gene; ESBLs: Extended-spectrum beta-lactamases.

The beneficial effect of Adansonia digitata products success to modulate lipid profiles and inhibit LDL oxidation in-vitro: An associational study.

Background: There is a growing interest in medicinal plants in recent years due to their many therapeutic benefits and low side effects. Among the medicinal plants is the African Adansonia digitata (baobab) that has edible fruit. In the current study, the effect of A. digitata juice consumption on the lipid profile was investigated. In addition, inhibition of the oxidation of low-density lipoprotein cholesterol (LDL-C) in-vitro by A. digitata essential oil (EO) was also investigated. Methods: In this cohort study, a total of 70 subjects of A. digitata users (AD group, 42 male and 28 female) and 70 non A. digitata users (Non-AD group, 44 male and 26 female) were recruited to participate in this study. We evaluated lipid profile, HbA1c, liver/kidney functions, and phytosterol contents in fasting blood samples of all participants. Results: The present findings illustrated significantly lower levels of total cholesterol, triglycerides, and LDL in the AD group compared to Non-AD (p < 0.01). In addition, essential oil of A. digitata inhibited LDL oxidation in-vitro as shown by the significant decreases in the formation of malonaldehyde (MDA), protein carbonyl (PC), and lipid hydroperoxide (LHP) (P<0.05). No significant changes in fasting blood glucose, HbA1c, HDL, kidney function, and liver function enzymes between the two groups were detected (P>0.05). Conclusion: The juice of A. digitata has hypolipidemic and antioxidative effects and might be beneficial for the management of lipid levels in the body.

Nano Zinc Versus Bulk Zinc Form as Dietary Supplied: Effects on Growth, Intestinal Enzymes and Topography, and Hemato-biochemical and Oxidative Stress Biomarker in Nile Tilapia (Oreochromis niloticus Linnaeus, 1758).

Five isonitrogenous diets were formulated to comprise two forms of zinc (Zn): convention zinc oxide named Bulk-ZnO or zinc oxide nanoparticles (Nano-ZnO) supplemented at two levels 30 and 60 mg kg-1 compared to the control diet. Nile tilapia, Oreochromis niloticus, fingerlings (5.02-5.05 g) were fed tested diets two times a day for 84 days. The results displayed that the best growth and digestive enzyme activity (P < 0.05) were noticed in fish fed 60 mg kg-1 Nano-ZnO. Moreover, significant (P < 0.05) improvement in intestinal topography was observed in 60 mg kg-1 Nano-ZnO group versus other treatments. Furthermore, fish fed 30 mg kg-1 Nano-ZnO recorded the best values of hematological indices (P < 0.05). The alanine and aspartate aminotransferase (ALT and AST) values were lower, while total serum protein, albumin, and globulin contents were clearly higher in fish fed diet that contained 30 mg kg-1 Nano-ZnO versus other groups. The significant highest values of oxidative enzyme activity escorted with lower malondialdehyde value recorded of fish fed diet supplemented with 60 mg kg-1 Nano-ZnO. The results indicated that inclusion of Nano-ZnO at 60 mg kg-1 was the recommended source to enhance growth, feed utilization, amylase and lipase enzymes activity, intestinal morphology, hemato-biochemical, and oxidative response biomarkers of Nile tilapia compared with Bulk-ZnO in commercial tilapia feeds.

Synchronous transurethral cystolitholapaxy and TURP reveals better results than transurethral cystolitholapaxy plus medical therapy for BPH: a randomized prospective study on 100 patients with concomitant urinary bladder stone(s) and BPH.

OBJECTIVE: This report presents the results of a randomized prospective study comparing synchronous transurethral cystolitholapaxy and transurethral resection of the prostate (TURP) with transurethral cystolitholapaxy plus medical treatment for benign prostatic hyperplasia (BPH) in patients with concomitant vesical stone(s) and BPH. PATIENTS AND METHODS: The study included 100 patients with bladder stone(s) < 2.5 cm associated with BPH. Eligible patients were divided randomly into two groups: group I (n = 50 patients) underwent simultaneous transurethral cystolitholapaxy and TURP, and group II (n = 50 patients) underwent transurethral cystolitholapaxy and received postoperative tamsulosin plus finasteride. RESULTS: The mean follow-up was 20.1 ± 5.3 months. No statistically significant differences were found between the 2 groups regarding the preoperative parameters (age, prostatic volume, bladder stone characteristics, prostate-specific antigen level, International Prostate Symptom Score, peak urinary flow rate, and post-void residual urine volume). Both groups experienced statistically significant postoperative improvement in IPSS, post-void residual (PVR) urine volume, and peak flow rate compared with the preoperative parameters (P < 0.001 for all parameters). However, patients in group 1 had a more pronounced improvement (P < 0.001 for all parameters). Thus, 15 patients in group 2 underwent TURP during follow-up. PVR urine and prostate volume predicted the failure of medical therapy and the need for TURP. CONCLUSION: Synchronous transurethral cystolitholapaxy and TURP revealed better results than transurethral cytolitholapaxy plus medical therapy. Cystolitholapaxy without TURP should not be indicated especially in patients with significant PVR urine volumes and larger prostates.
