Indocyanine green-enhanced transpupillary thermotherapy for juxtapapillary retinal capillary hemangioblastoma.

PURPOSE: To study the clinical presentation and treatment outcomes of indocyanine green-enhanced transpupillary thermotherapy (ICG-TTT) for treatment-naïve juxtapapillary retinal capillary hemangioblastoma (JRCH). METHODS: A prospective interventional case series. The technique involved ICG dye infusion 45 seconds prior to application of TTT. The main study outcomes were local tumor control, resolution of subretinal fluid (SRF), and improvement in best-corrected visual acuity (BCVA). RESULTS: Eight eyes of seven patients (5 males and 2 females) were included. The mean age was 26 years (range: 5-56 years). Systemic evaluation revealed von-Hippel Lindau (VHL) disease in five patients. The most common location was the temporal aspect of the optic disc (5 eyes). The mean basal diameter was 2.9 mm (range: 1-8 mm), and tumor thickness was 1.4 mm (range: 1-4 mm). All eight eyes were treated with multiple sessions of ICG-TTT (mean: 3 sessions). Six eyes received adjuvant intravitreal injection of dexamethasone implant (4 eyes) and/or bevacizumab (4 eyes). Post treatment, six eyes (75%) had tumor regression with reduction of SRF. One eye had a partial response with persisting SRF, and one eye showed poor response to TTT for which external beam radiotherapy was performed. At the last follow-up (median: 11 months; range: 6-29 months), the BCVA remained stable in seven eyes and improved in one eye (hand motion to 20/40). CONCLUSION: Multiple ICG-TTT sessions can be considered as an alternative treatment option for JRCH with effective local tumor control and SRF resolution.

A Combinational Therapy for Preventing and Delaying the Onset of Alzheimer's Disease: A Focus on Probiotic and Vitamin Co-Supplementation.

Alzheimer's disease is a progressive neurodegenerative disorder with a complex etiology, and effective interventions to prevent or delay its onset remain a global health challenge. In recent years, there has been growing interest in the potential role of probiotic and vitamin supplementation as complementary strategies for Alzheimer's disease prevention. This review paper explores the current scientific literature on the use of probiotics and vitamins, particularly vitamin A, D, E, K, and B-complex vitamins, in the context of Alzheimer's disease prevention and management. We delve into the mechanisms through which probiotics may modulate gut-brain interactions and neuroinflammation while vitamins play crucial roles in neuronal health and cognitive function. The paper also examines the collective impact of this combinational therapy on reducing the risk factors associated with Alzheimer's disease, such as oxidative stress, inflammation, and gut dysbiosis. By providing a comprehensive overview of the existing evidence and potential mechanisms, this review aims to shed light on the promise of probiotic and vitamin co-supplementation as a multifaceted approach to combat Alzheimer's disease, offering insights into possible avenues for future research and clinical application.

Successful Use of Cefepime-Zidebactam (WCK 5222) as a Salvage Therapy for the Treatment of Disseminated Extensively Drug-Resistant New Delhi Metallo-ß-Lactamase-Producing Pseudomonas aeruginosa Infection in an Adult Patient with Acute T-Cell Leukemia.

With limited and often toxic treatment options, carbapenem-resistant Gram-negative infections are associated with significant mortality. Cefepime-zidebactam is a promising antibiotic option undergoing a phase 3 trial that has activity against diverse antibiotic-resistant mechanisms in Gram-negative pathogens due to its ß-lactam enhancer mechanism, mediating multiple PBP binding. We report a case of disseminated infection caused by a New Delhi metallo-ß-lactamase-producing, extensively drug-resistant Pseudomonas aeruginosa isolate in a patient with acute T-cell leukemia, successfully managed with cefepime-zidebactam as a salvage therapy.

Sharp-edged pencil type ZnO flowers and BiOI flakes combined with carbon nanofibers as heterostructured hybrid photocatalysts for the removal of hazardous pollutants from contaminated water.

The growth of advanced micro-and nanostructures with metal oxides has consistently generated extraordinary interest in energy and environmental applications. Cutting-edge nanostructures exhibit superior reactive sites and surface areas, thus improving the performance in crucial domains. In this study, sharp-edged pencil-type ZnO flowers and BiOI flakes as pristine materials, and their composition with carbon nanofibers (CNFs) (ZnO-BiOI@CNFs) as a hetero hybrid catalyst as well as binary compositions such as ZnO-BiOI, ZnO@CNFs, and BiOI@CNFs catalysts were fabricated using a simple and convenient hydrothermal synthesis process. The composition of newly produced innovative nanostructures was examined for azo dye degradation under solar simulator exposure. Dye degradation of ∼95% was achieved by the hybrid catalyst (ZnO-BiOI@CNFs) during 120 min of irradiation, which was ∼1.8 and 2.1-times higher than pristine ZnO and BiOI nanostructures, respectively. The improved hybrid catalysts were able to degrade methyl orange (MO) and rhodamine B (RhB) dyes. Importantly, mixed dyes RhB, MO, and azo dye demonstrated 47% dye degradation using a hybrid catalyst. These mixed dye-scalable hybrid catalyst performances offer additional insights into commercialization/industrialization. The outstanding performance of the hybrid catalyst is attributed to the unidirectional electron flow with pencil-like ZnO, a catalyst with a larger absorption zone, high surface area, and reactive sites, particularly ZnO and BiOI nanostructures, and decreased recombination rate with a heterojunction interface. In addition, CNFs can operate as electron traps and sinks, providing very quick redox reactions. To produce the sophisticated nanostructures with homogeneous morphologies, this work presents new insights into energy and environmental applications.

Developing and demonstrating an atomistic and holistic model of anthropometric failure among children under five years of age using the National Family Health Survey (NFHS)-5 data from India.

Introduction: Composite Index of Anthropometric Failure (CIAF) and its further modifications have not incorporated all the combinations of malnutrition. We propose a new model incorporating all the forms of malnutrition among children under five years of age. However, the current models might misclassify a growing child as malnourished. Our objective is to develop a comprehensive scoring system using the three anthropometric Z-scores [height-for-age (HAZ), weight-for-age (WAZ), and weight-for-height (WHZ) Z-scores] and demonstrate the proposed CIAF model using the National Family Health Survey-5 (NFHS-5) data from India. Methods: A new scoring system was developed using the WAZ, HAZ, and WHZ scores to determine the child's nutritional status. We also proposed a new CIAF model by including all possible categories of malnutrition and practically demonstrated it using the NFHS-5 dataset after applying the new scoring system. Under-five children with heights, weights, and ages available were included in the analysis. The groups of malnutrition are presented as weighted proportions before and after applying the new score to the proposed model. Results: Our final analysis included individual-level data of 198,802 children under five years of age (weighted N = 195,197). After applying the new scoring system to the proposed model, the prevalence of stunting has reduced to 11.8% (95% CI 11.66-11.94) from 13.2% (95% CI 13.09-13.39) and wasting prevalence has reduced to 4.9% (95% CI 4.85-5.04) from 6.4% (95% CI 6.29-6.51). The most common forms of anthropometric failures among Indian children by using the newly developed CIAF model are: "Stunting and underweight" (30,127; 15.4%), Stunting only (23,035; 11.8%), and "wasting and underweight" (14,698; 7.5%). We found a new category called "Stunting, underweight, and overweight" (stunting = HAZ < -2SD, underweight = WAZ < -2SD, overweight = WHZ > +2SD). It constituted 0.1% (220 children) of the total sample. Conclusion: When the new scoring system is applied to the proposed CIAF model, it captures all forms and combinations of malnutrition among under-five children without overlap and prevents misclassifying a growing child as malnourished. The newly identified category shows that stunting (HAZ < -2SD), overweight (WHZ > +2SD) and underweight (WAZ < -2SD) can co-exist in the same child.

A Combination Therapy of Urolithin A+EGCG Has Stronger Protective Effects than Single Drug Urolithin A in a Humanized Amyloid Beta Knockin Mice for Late-Onset Alzheimer's Disease.

In the current study, for the first time, we study mitophagy enhancer urolithin A and a combination of urolithin A+green tea extract EGCG against human Aß peptide-induced mitochondrial and synaptic, dendritic, inflammatory toxicities and behavioral changes in humanized homozygous amyloid beta knockin (hAbKI) mice of late-onset Alzheimer's disease (AD). Our findings reveal significantly increased positive effects of urolithin A and a combination treatment of urolithin A+EGCG in hAbKI mice for phenotypic behavioral changes including motor coordination, locomotion/exploratory activity, spatial learning and working memory. mRNA and protein levels of mitochondrial fusion, synaptic, mitophagy and autophagy genes were upregulated, and mitochondrial fission genes are downregulated in urolithin A and combine treatment in hAbKI mice; however, the effect is stronger in combined treatment. Immunofluorescence analysis of hippocampal brain sections shows similar findings of mRNA and protein levels. Mitochondrial dysfunction is significantly reduced in both treatment groups, but a stronger reduction is observed in combined treatment. Dendritic spines and lengths are significantly increased in both treatment groups, but the effect is stronger in combined treatment. The fragmented number of mitochondria is reduced, and mitochondrial length is increased, and mitophagosomal formations are increased in both the groups, but the effect is stronger in the combined treatment. The levels of amyloid beta (Aß) 40 and Aß42 are reduced in both treatments, however, the reduction is higher for combined treatment. These observations suggest that urolithin A is protective against human Aß peptide-induced toxicities; however, combined treatment of urolithin A+EGCG is effective and stronger, indicating that combined therapy is promising to treat late-onset AD patients.

Targeting mitochondrial bioenergetics as a promising therapeutic strategy in metabolic and neurodegenerative diseases.

Mitochondria are the organelles that generate energy for the cells and act as biosynthetic and bioenergetic factories, vital for normal cell functioning and human health. Mitochondrial bioenergetics is considered an important measure to assess the pathogenesis of various diseases. Dysfunctional mitochondria affect or cause several conditions involving the most energy-intensive organs, including the brain, muscles, heart, and liver. This dysfunction may be attributed to an alteration in mitochondrial enzymes, increased oxidative stress, impairment of electron transport chain and oxidative phosphorylation, or mutations in mitochondrial DNA that leads to the pathophysiology of various pathological conditions, including neurological and metabolic disorders. The drugs or compounds targeting mitochondria are considered more effective and safer for treating these diseases. In this review, we make an effort to concise the available literature on mitochondrial bioenergetics in various conditions and the therapeutic potential of various drugs/compounds targeting mitochondrial bioenergetics in metabolic and neurodegenerative diseases.

De-oiled palm kernel cake for stall-fed buffaloes: effect on milk constituents, nutrient digestibility, biochemical parameters, and rumen fermentation.

Palm kernel cake, the main by-product of the palm kernel oil extraction process, is a highly available and low-priced agro-industrial by-product. However, several concerns exist to arriving at a safe inclusion level, especially for buffaloes. Two experiments were conducted to evaluate the effects of feeding de-oiled palm kernel cake (DPKC) to tropical buffaloes. In trial I, four fistulated Murrah buffaloes arranged in a 4 × 4 Latin square design were fed diets containing DPKC inclusions at 0, 15, 30, and 45% levels of compound feed to study their effects on rumen fermentation parameters. Trial II involves feeding twelve lactating buffaloes with DPKC inclusion levels at 0 or 15% of the compound feed to evaluate the effect of DPKC on the nutrient digestibility, serum biochemical constituents, rumen fermentation patterns, and lactation profile. The DPKC diets did not affect rumen pH, TCA-ppt nitrogen, and TVFA proportion; nevertheless, the NH3-N data revealed a decreased trend (P = 0.076). The acetate fraction decreased linearly (P < 0.05) with increased DPKC diets. Replacing the conventional protein sources with DPKC at a 15% level did not influence the nutrient intake and digestibility coefficients. No significant effects were observed for serum biochemical and mineral profiles of the lactating buffaloes fed the DPKC diet. Neither milk yield nor milk constituents (SNF, total solids, density, lactose, protein) were altered with the diets fed, except for milk fat%, which tended to increase (P = 0.092) on feeding DPKC diets. All the lactation parameters varied with time of collection, and diet × time interactions were noticed for fat, density, protein, 6% FCM yield, and butterfat yield. The feed efficiency tended to increase (P = 0.070) in the buffaloes fed DPKC diets. The profit margins were ₹6.07 and ₹1.63 for the DPKC included diets and feed cost per Kg 6% FCMY, respectively. In  conclusion, the inclusion of DPKC in the diet decreases feed cost without affecting the nutrient intakes, digestibility coefficients, serum biochemical and mineral profile, and lactation parameters.

Primary Macular Retinoblastoma: Clinical Presentation and Treatment Outcomes.

Purpose: To describe the clinical features and treatment outcomes in eyes with primary macular retinoblastoma (RB). Methods: Patients with primary macular RB were analyzed. Results: Of 41 patients (47 eyes), 20 (49%) were boys and 21 (51%) were girls. The mean age at diagnosis was 16 months (range, 1-60 months). The RB was bilateral in 6 patients (15%). At presentation, the macula was completely covered with the tumor in 22 eyes (47%) and partially covered with the fovea spared in 13 eyes (28%) and the fovea involved 12 eyes (25%). Based on the International Classification of Intraocular Retinoblastoma, 25 (53%), 15 (32%), and 7 (15%) of tumors were in Group B, Group C, and Group D, respectively. The tumor had exophytic features in 36 eyes (77%). The mean tumor basal diameter was 10.0 mm and the mean thickness, 5.6 mm. Associated features included subretinal seeds (10 eyes; 21%) and surrounding subretinal fluid (16 eyes; 34%). Forty-three eyes (92%) were treated with intravenous chemotherapy, 2 (4%) with intra-arterial chemotherapy, and 2 (4%) with transpupillary thermotherapy. Local tumor control was achieved in 45 eyes (96%), with 33 eyes (70%) showing a type III regression pattern. Over a mean follow-up of 23 months (range, 3-48 months), the macular tumor recurred in 5 eyes (11%), the globe was salvaged in all eyes with associated foveal atrophy (36 eyes; 77%), and 1 patient (2%) died. Conclusions: Macular RB has a good prognosis for globe salvage while vision salvage might be compromised as a result of associated foveal atrophy.

Dietary Supplementation of Nano Zinc Oxide on Performance, Carcass, Serum and Meat Quality Parameters of Commercial Broilers.

An experiment was conducted to evaluate the effect of supplementation of zinc in the diet in the form of nano zinc oxide (nano ZnO) on the performance of broilers. A total of 240 day-old commercial broiler chicks were distributed in a completely randomized design into 6 treatments with 8 replicates of 5 chicks each. Treatments comprised of T1- basal diet (BD) without ZnO supplementation, T2- 2.5 ppm ZnO, T3- 5 ppm ZnO, T4- 10 ppm ZnO, T5- 20 ppm ZnO, and T6- 40 ppm inorganic ZnO. The results revealed that supplementation of nano ZnO at 2.5 ppm recorded significantly (P < 0.05) higher body weight gain, feed intake, and better feed conversion ratio (FCR) compared to control and other treatment groups at 42 days of age. All dietary treatments failed to exert any significant (P > 0.05) effect on various carcass parameters (dressing percentage, abdominal fat, giblet yields), serum protein and cholesterol concentrations, and meat quality parameters (water holding capacity and pH) of broiler chicken at 42 days of age. Finally, it could be concluded that supplementation of nano ZnO at 2.5 ppm improved the performance of broilers.

Improvement in Glycemic Control in Mice of Different Age Groups.

AIMS AND METHODS: The declining ability to control blood glucose with advancement of age is an important health risk factor and may lead to insulin resistance, type-2-diabetes and Alzheimer's disease. Adenovirus 36(Ad36) improves glycemic control independent of insulin signaling(insulin sparing effect) as evidenced by cell, animal and observational human studies. This property of Ad36 may be useful in correcting aging-related glucose intolerance and related health conditions. Therefore, we determined the effect of Ad36 on glycemic control in older mice, to identify the age group that best responds to Ad36. Six, 12 or 20-month old C57Bl/6 mice on chow diet were each divided into weight-matched groups(mock-infected or Ad36-infected). Body weight was recorded weekly post infection (p.i.) and fasting glucose measured(week 0, 4, 8 and 20 p.i.). Blood glucose and serum insulin were measured during glucose tolerance test(week 0 and 16 p.i.). At week 20 p.i., animals were sacrificed, blood and tissues collected. RESULTS: Mice from all age groups showed improvement in glucose clearance post Ad36 infection, but a more profound effect was observed in 6-month old mice compared with mock-infected mice. Under fed conditions though there was no difference in blood glucose at 20 wk p.i., interestingly, Ad36 reduced serum insulin in age groups old mice, compared with control mice. CONCLUSIONS: These findings suggest Ad36 infected animals improve glycemic control and clear post-prandial gluco00000se increase without increasing insulin secretion in an insulin sparing manner. These beneficial effects provide strong evidence for developing Ad36-based approaches as a novel tool to attenuate age associated glucose intolerance.

Health care seeking behaviour among rural women in Telangana: A cross sectional study.

BACKGROUND: The health of women is of particular concern because, in many societies, they are disadvantaged by discrimination rooted in sociocultural factors. Women need to breach many social barriers to empower and to get access for quality health care services. Health seeking behavior is one of the important determinants of women health. OBJECTIVES: To assess healthcare seeking behavior among rural women in Telangana. METHODS: Cross-sectional study with sample size of 200 was conducted in three villages attached to a medical college. Women of aged 20 years and above were included in the study. Data was collected by predesigned pretested semi-structured questionnaire. Data was presented in proportions with confidence interval and Chi-square test was applied to find the association between variables by using SPSS ver. 23. RESULTS: Only 34.5% [95% CI: 27.9, 41.5] of the subjects seek medical care as soon as symptoms appear and 69% [95% CI: 62.1, 75.3] of the participants were aware of nearby functioning health centres. Majority (60.5%) of the subjects Visits qualified medical practitioner during illness. CONCLUSIONS: The present study found that there is still a need to create awareness about the importance of healthcare and available health centers as significant proportion of women population approached unqualified medical practitioners and seeking home remedies as first consultancy source for their health remedies.

Effect of vitamin B12 supplementation on retinal lesions in diabetic rats.

Purpose: Diabetic retinopathy (DR) is the most common complication of diabetes involving microvasculature and neuronal alterations in the retina. Previously, we reported that vitamin B12 deficiency could be an independent risk factor for DR in humans. However, the effect of vitamin B12 supplementation in experimental DR is unknown. Thus, in this study, we investigated the impact of dietary supplementation of vitamin B12 on retinal changes in diabetic rats. Methods: Diabetes was induced in 2-month-old Sprague-Dawley rats and maintained for 4 months. One group of diabetic rats were fed normal levels of vitamin B12, and one group double the quantity of vitamin B12 (50 µg/kg diet). Vitamin B12 and homocysteine levels in the plasma were analyzed with radioimmunoassay (RIA) and high-performance liquid chromatography (HPLC), respectively. At the end of 4 months of experimentation, the eyeballs were collected. Retinal changes were analyzed with hematoxylin and eosin (H&E) staining, immunoblotting, and immunofluorescence methods. Results: Dietary supplementation of vitamin B12 had no effect on food intake, bodyweight, fasting blood glucose, and plasma homocysteine levels in the diabetic rats. However, vitamin B12 supplementation prevented loss of rhodopsin, and overexpression of VEGF, and completely prevented overexpression of HIF1α, GFAP, and endoplasmic reticulum (ER) stress markers (GRP78, ATF6α, XBP1, CHOP, and caspase 12) in the diabetic rat retina. Further, vitamin B12 ameliorated apoptosis in the retina as shown with terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) and prevented retinal thinning. Conclusions: Vitamin B12 supplementation of diabetic rats appeared to be beneficial by circumventing retinal hypoxia, VEGF overexpression, and ER stress-mediated cell death in the retina. The present study adds another potential therapeutic strategy of vitamin B12 in diabetes.

INDOOR RADON AND THORON IN THE VICINITY OF PROPOSED URANIUM MINING SITE: A CASE STUDY AT DASARLAPALLY VILLAGE, TELANGANA STATE, INDIA.

Studies are being conducted for the past few decades in and around the uranium mining sites across the globe to identify environmental nuclear radiation risk to the common public. The area near Dasarlapally village was identified for uranium exploration by the AMDER, Hyderabad. The present study was carried out to measure the indoor radon and thoron activity concentrations in the dwellings of Dasarlapally village. For this purpose different types of dwellings were chosen randomly across the village. The measured annual average concentration of radon and thoron in dwellings were found to be 141 ± 42 and 139 ± 77 Bqm-3, respectively, and the calculated annual effective inhalation dose due to radon was determined to be 3.5 mSv. Seasonal variation and diurnal variation of radon and thoron activity concentration were investigated. The variation of radon and thoron activity concentration in different types of dwellings was also studied, and the variation was found to be statistically insignificant. The uncertainty propagated in the effective inhalation dose due to thoron was discussed.

Behavioral and neurochemical consequences of perinatal exposure to lead in adult male Wistar rats: protective effect by Centella asiatica.

The present study evaluated the protective effects of Centella asiatica (CA) leaf extract on behavioral deficits and neurotoxicity in adult rat exposed to lead during perinatal period. Adult Wistar rats were exposed to 0.15% lead acetate (Pb) from gestation day 6 through drinking water and the pups were exposed lactationally to Pb till weaning. Significant perturbations in locomotor activity and exploratory behavior were observed in rats exposed to Pb during perinatal period. The levels of lipid peroxidation increased significantly with a reduction in levels of glutathione and activity levels of acetylcholinesterase and antioxidant enzymes in hippocampus, cerebrum, cerebellum, and medulla of brains excised from Pb-exposed rats. Oral supplementation of CA during postweaning period provided significant protection against Pb-induced behavioral impairments and neurotoxicity, without chelating tissue Pb levels. The possible neuroprotective efficacy of CA may be due to its antioxidant potential but not by lowering effects of brain Pb content.

Protective Effects of Indian Spice Curcumin Against Amyloid-ß in Alzheimer's Disease.

The purpose of our article is to assess the current understanding of Indian spice, curcumin, against amyloid-ß (Aß)-induced toxicity in Alzheimer's disease (AD) pathogenesis. Natural products, such as ginger, curcumin, and gingko biloba have been used as diets and dietary supplements to treat human diseases, including cancer, cardiovascular, respiratory, infectious, diabetes, obesity, metabolic syndromes, and neurological disorders. Products derived from plants are known to have protective effects, including anti-inflammatory, antioxidant, anti-arthritis, pro-healing, and boosting memory cognitive functions. In the last decade, several groups have designed and synthesized curcumin and its derivatives and extensively tested using cell and mouse models of AD. Recent research on Aß and curcumin has revealed that curcumin prevents Aß aggregation and crosses the blood-brain barrier, reach brain cells, and protect neurons from various toxic insults of aging and Aß in humans. Recent research has also reported that curcumin ameliorates cognitive decline and improves synaptic functions in mouse models of AD. Further, recent groups have initiated studies on elderly individuals and patients with AD and the outcome of these studies is currently being assessed. This article highlights the beneficial effects of curcumin on AD. This article also critically assesses the current limitations of curcumin's bioavailability and urgent need for new formulations to increase its brain levels to treat patients with AD.

Antibacterial and anti-inflammatory properties of Plantago ovata Forssk. leaves and seeds against periodontal pathogens: An in vitro study.

BACKGROUND: Plantago commonly called as Isabgol (Plantago ovata Forssk.) is a perennial herb that belongs to the family Plantaginaceae. A range of biological activities has been found from plant extracts, including wound healing activity, anti-inflammatory, analgesic, antioxidant, weak antibiotic, immunomodulating and anti-ulcerogenic activity. Periodontal disease is a complex condition as a result of interaction between microorganisms and host inflammatory mediators. Hence, the extract of Isabgol is tested for its antibacterial and anti-inflammatory properties against periodontal disease. AIM: The aim of this in vitro study is to evaluate the antibacterial property of Isabgol leaves and seeds against periodontal pathogens, namely Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, and Fusobacterium nucleatum and anti-inflammatory property against matrix metalloproteinase-2 (MMP-2) and MMP-9. MATERIALS AND METHODS: In this in vitro study, aqueous extract of Isabgol is tested for its antibacterial property against the stock cultures of specified periodontal pathogens using the tube dilution method and anti-inflammatory property against MMP-2 and MMP-9 using zymogen gel electrography. RESULTS: Minimum concentration at which the sensitivity of A. actinomycetemcomitans, P. gingivalis, P. intermedia, and F. nucleatum for the extract observed was 50 µl/ml, 0.8 µl/ml, 0.4 µl/ml and 12.5 µl/ml, respectively, concentrations below these showed no effect on the microorganisms. Zymogen electrographic test for anti-inflammatory activity showed percentage inhibition of 30% and 40% against MMP-2 and MMP-9, respectively. CONCLUSION: Isabgol is effective against the periodontal pathogens and inflammatory mediators which are responsible for periodontal disease.

A review on the effects of current chemotherapy drugs and natural agents in treating non-small cell lung cancer.

Lung cancer is the leading cause of cancer deaths worldwide, and this makes it an attractive disease to review and possibly improve therapeutic treatment options. Surgery, radiation, chemotherapy, targeted treatments, and immunotherapy separate or in combination are commonly used to treat lung cancer. However, these treatment types may cause different side effects, and chemotherapy-based regimens appear to have reached a therapeutic plateau. Hence, effective, better-tolerated treatments are needed to address and hopefully overcome this conundrum. Recent advances have enabled biologists to better investigate the potential use of natural compounds for the treatment or control of various cancerous diseases. For the past 30 years, natural compounds have been the pillar of chemotherapy. However, only a few compounds have been tested in cancerous patients and only partial evidence is available regarding their clinical effectiveness. Herein, we review the research on using current chemotherapy drugs and natural compounds (Wortmannin and Roscovitine, Cordyceps militaris, Resveratrol, OSU03013, Myricetin, Berberine, Antroquinonol) and the beneficial effects they have on various types of cancers including non-small cell lung cancer. Based on this literature review, we propose the use of these compounds along with chemotherapy drugs in patients with advanced and/or refractory solid tumours.

Altered spermatogenesis, steroidogenesis and suppressed fertility in adult male rats exposed to genistein, a non-steroidal phytoestrogen during embryonic development.

This article focuses on the effects of prenatal exposure to genistein on the mother, her pregnancy and reproductive functions of the male progeny, since these issues have ethological relevance in both animals and humans. Pregnant Wistar rats received i.p. injections of genistein at a dose level of 2, 20 or 100 mg/kg body weight daily from 12th to 19th day of gestation. Male pups from control and genistein exposed animals were weaned and allowed to develop until 100 days of age; however, when they were 90 days old, twelve males from each group were cohabited with untreated 90-day old females for 8 days. Results revealed a significant decrease in indices of reproductive organs in adult male rats exposed to genistein during embryonic development. Dose dependent reduction was observed in daily sperm production and epididymal sperm density and quality in genistein treated rats. Significant decrease was observed in the activity levels of 3ß- and 17ß-hydroxysteroid dehydrogenases in testis of experimental rats with a decline in plasma testosterone levels. Histological examination of testis of genistein treated rats indicated deterioration in testicular architecture. In the fertility study, the mean number of implantations and live fetuses per dam mated with 100 mg genistein exposed males was reduced.

The protective effects of zinc in lead-induced testicular and epididymal toxicity in Wistar rats.

The aim of this study was to investigate the beneficial effects of zinc (Zn) in preventing lead (Pb)-induced reproductive toxicity in Wistar rats. The rats were divided into four groups, namely, control group, Pb group, Zn group, and Pb + Zn group. Animals were exposed to Pb (819 mg of Pb/L) or Zn (71 mg of Zn/L) or both through drinking water for 65 days. Rats exposed to Pb showed decreased weights of testes and accessory sex organs. Significant decrease in the testicular daily sperm production, epididymal sperm count, motility, viability, and number of hypoosmotic tail coiled sperm was observed in Pb-exposed rats. Testicular 3ß- and 17ß-hydroxysteroid dehydrogenase activity levels and circulatory testosterone levels were also decreased significantly in Pb-exposed rats. A significant increase in the lipid peroxidation products with a significant decrease in the activities of catalase and superoxide dismutase were observed in the testes and epididymis of Pb-exposed rats. Moreover, the testicular architecture showed lumens devoid of sperm in Pb-exposed rats. Supplementation of Zn mitigated Pb-induced oxidative stress and restored the spermatogenesis and steroidogenesis in Pb-exposed rats. In conclusion, cotreatment of Zn is effective for recovering suppressed spermatogenesis, steroidogenesis, elevated oxidative status, and histological damage in the testis of rats treated with Pb.
