Effect of amla and ginger powders on quality criteria of African catfish (Clarias gariepinus) fingers.

Catfish (Clarias gariepinus) meat isn't preferred by consumers in compared to other fish species meat, thus to enhance the use of catfish meat, ready to eat catfish fingers were prepared with some plants additives (amla and ginger powder). The mean objective of this study was to assess the impact of amla and ginger powder on catfish finger qualities in terms of physical, chemical, microbiological, and sensorial parameters under stored at a low temperature (5 ± 1 °C). The obtained results were compared with those of a control sample (basic formula) and a sample containing the synthetic antioxidant. During the storage period, the levels of pH, thiobarbituric acid, total volatile basic nitrogen, trimethylamine, total bacteria count, psychrophilic bacteria, molds and yeasts counts increased dramatically, although the values remained within acceptable ranges. The findings also revealed, that amla and ginger powder considerably (p < 0.05) reduced the changes in quality parameters, as well as there was a considerable increase in the quality parameter in all treated samples than in the control. Finally, amla and ginger powder can be a substitute for synthetic antioxidants and antimicrobials. These findings suggest that the powder of amla and ginger are suitable for use as a natural antioxidants and antimicrobials to extend the shelf-life of animal products.

Conservative Approach is Safe for Perfused-Pulseless Hands Following Blunt Brachial Artery Injury in Children.

Blunt trauma of the brachial artery (BA) in pediatric age is often associated with neurological and orthopaedic injuries. Acute ischemic hands warrant immediate exploration, but the management of warm-pulseless hands following elbow trauma is controversial. This study evaluates the role of conservative treatment of blunt BA injuries in children with non-threatened hands. Eleven children with blunt trauma onto the BA having warm-pulseless hands were studied retrospectively. After a mean follow-up period of 2.5 ± 0.9 years, all cases had thorough clinical examination and duplex scan to assess the treatment outcomes. At the end of follow-up period, all subjects had well-perfused hands with intact wrist pulses. The duplex scan revealed those who had interposition grafts to be patent and one case had an aneurysmal dilatation. There was no statistical significance difference between affected and healthy forearms regarding the mean peak systolic velocity at the wrist, affected side was 62 ± 0.82 cm/s versus 68 ± 0.57 cm/s for opposite side ( p -value = 0.14). Patients with blunt BA trauma and warm-pulseless hands could be managed safely with conservative treatment, leaving surgical exploration for those who did not regain pulses after 48 hours. Duplex ultrasound can safely verify the patency of surgical repair and can be used for surveillance to detect future complications.

The intraoperative use of a calliper predicts leg length and offset after total hip arthroplasty. Component subsidence influences the leg length.

BACKGROUND: The purpose of total hip arthroplasty (THA) post-surgery and proper physiotherapy is positive recovery for the patient. Consideration is given to hip replacement biomechanics by ensuring no discrepancies in limb length (LL) and a stable prosthesis. Therefore, the patient must have proper preoperative planning and communication and a clear understanding of what to expect. METHODS: A prospective series of 59 THA operated by a single surgeon via Hardinge approach was studied, using an intraoperative calliper (CAL) to predict the change of LL and offset. We compared the results of the intraoperative changes before and after THA implantation with the reference of these values on anteroposterior x-ray pelvis. The importance of leg length balance and a good offset restoration is questioned, and the effect of component subsidence on leg length is considered. RESULTS: The average preoperative leg length discrepancy was -6.0 mm, postoperatively +3.6 mm. There was a strong correlation between the CAL measurements and the values on the x-ray (LL, r=0.873, p<0.01; offset, r=0.542, p<0.01). Reliability is better for limb length than for offset. These results are comparable within the literature and the statistical results from other studies reviewed. In addition, we evaluate the importance of subsidence of the prosthesis components for long-term results. CONCLUSION: The intraoperative use of CAL gives excellent results in predicting the final LL and offset after THA. Considering subsidence of prosthesis components, a target zone around +5 mm might be more suitable for leg length directly postoperatively. Moreover, surgeons must discuss the topic of leg length discrepancy (LLD) intensively with the patient pre-operatively. LEVEL OF EVIDENCE: Level 4, prospective cohort study.

Intra-articular gold induced cytokine (GOLDIC®) injection therapy in patients with osteoarthritis of knee joint: a clinical study.

PURPOSE: To evaluate the safety and efficacy of a novel technique of preconditioning autologous blood with gold particles (GOLDIC®) and injection in patients with moderate to severe knee osteoarthritis (KOA). METHODS: During this phase 2a, proof-of-concept (PoC) open label study, 83 consecutive patients that 64 patients met inclusion criteria (mean age: 64.8 years; 89 knees) with radiographically proven KOA, received four ultrasound guided intra-articular knee injections of GOLDIC® at three to six day intervals. Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Knee injury and Osteoarthritis Outcome Score (KOOS) were evaluated at baseline, four weeks, three, six months, one, two and four years (T1-T6). The incidence of treatment related severe adverse events (SAEs) recorded. Intra-articular gelsolin level in patients with effusion was determined. RESULTS: KOOS and WOMAC scores improved for the full duration of the study (P < 0.05), minimal clinically important difference (MCID) was observed at all time points in all KOOS subscores, with no reported SAEs. Intra-articular gelsolin level increased after treatment with reduction of effusion. No statistically significant evidence of an association between patient demographics and outcome were identified. Nine patients failed treatment, with 32 months mean time to failure and underwent total knee arthroplasty. CONCLUSION: PoC study of GOLDIC® as a novel device for conservative management of moderate to severe KOA was confirmed. GOLDIC® produces rapid and sustained improvements in all indices after treatment, with no SAEs.

Gold-Induced Cytokine (GOLDIC®) Injection Therapy in Patient with Plantar Fasciosis: A Case Report.

A novel technique of cultivating autologous blood with gold particles; then separating the gold particles and cells from the serum and injecting the conditioned serum into affected plantar fascia. A first-time report of the safety and efficacy in treatment of recalcitrant plantar fasciosis in an Olympic equestrian. A single patient with clinical signs, symptoms and ultrasound evidence of plantar fasciosis was treated with four intra-ligamentous GOLDIC® injection therapy. The Olympic jumper was evaluated by Visual Analog Scale (VAS), Foot and Ankle Disability Index (FADI), and Global Rating of Change (GRoC) score(s) before injection and at 6-month follow-up. VAS, FADI, and GRoC scores showed substantial and marked improvement clinically. The subject was able to return to sport without limitations after 8 weeks. The initial result demonstrates that the treatment regimen is safe, and efficacious. The subject demonstrated reduction of pain, and improved function that allowed return to high level competition.

Genus Ziziphus: A comprehensive review on ethnopharmacological, phytochemical and pharmacological properties.

ETHNOPHARMACOLOGICAL RELEVANCE: The genus Ziziphus (Rhamnaceae) contains 58 accepted species that are extensively used by local people and medicinal practitioners in arid and semi-arid regions for the treatment of diarrhoea, dysentery, cholera, diabetic, hypertension, inflammation, intestinal spasm, liver, malaria and other diseases. Aims of this review: This review article documents and critically assesses, for the first time; up to date categorized information about botanical traits, distribution, traditional uses, phytochemistry, pharmacological and toxicological effects of Ziziphus species. METHODS: Information was collected systematically from electronic scientific databases including Google Scholar, Science Direct, PubMed, Web of Science, ACS Publications, Elsevier, SciFinder, Wiley Online Library and CNKI, as well as other literature sources (e.g., books). KEY FINDINGS: The phytochemical investigations of plants of this genus have led to the identification of about 431 chemical constituents. Cyclopeptide alkaloids and flavonoids are the predominant groups. The crude extracts and isolated compounds exhibit a wide range of in vitro and in vivo pharmacologic effects, including antimicrobial, antitumour, antidiabetic, antidiarrhoeal, anti-inflammatory, antipyretic, antioxidant and hepatoprotective activities. Toxicity studies indicate that Ziziphus species seems to be non-toxic at typical therapeutic doses. CONCLUSION: Phytochemical and pharmacological studies have demonstrated that Ziziphus species are important medicinal herbs with prominent bioactivities. The focus so far has only been on ten species; however, plants of this genus can potentially yield a wide range of other products with different properties. Meticulous studies on pharmaceutical standardisation, mode of action of the active constituents and toxicity of Ziziphus species are needed to meet the growing demands of the pharmaceutical industry and to exploit their preventive and therapeutic potential fully.

Diaphragm-sparing effect of the infraclavicular subomohyoid block vs low volume interscalene block. A randomized blinded study.

BACKGROUND: Both low volume interscalene and infraclavicular-subomohyoid blocks were suggested to provide shoulder analgesia with low risk of phrenic nerve block. The aim of this study was to compare the frequency of the phrenic nerve block between these two techniques. METHOD: Seventy-two patients scheduled for shoulder arthroscopy were included in this randomized controlled blind study. Before induction of general anesthesia, patients received low volume interscalene block using 5 mL of ropivacaine 0.5% (LVS group) or infraclavicular-subomohyoid block using 25 mL of ropivacaine 0.5% (ISO group). The diaphragmatic excursion was measured (using ultrasound) before the block and after surgery. If the ratio of postoperative to pre-block excursions was <25%, a phrenic nerve block was concluded. Secondary outcomes were: the duration of analgesia, the 24-hour morphine requirement, and patient satisfaction. RESULTS: The phrenic nerve was blocked in 88.9% of patients in LVS group vs 5.6% in ISO group (P < 0.001). There was no significant difference between the two groups with regard to the duration of analgesia, the morphine consumption, and the patient satisfaction. CONCLUSION: Compared with the low volume interscalene block, the infraclavicular subomohyoid block resulted in a significantly less frequent phrenic nerve block and with no difference in postoperative analgesia. Therefore, it may be relevant to consider for patients who cannot tolerate a phrenic nerve block.

Pulsed Ultrasounds Reduce Pain and Disability, Increasing Rib Fracture Healing, in a Randomized Controlled Trial.

INTRODUCTION: Rib fractures are an important health issue worldwide, with significant, pain, morbidity, and disability for which only symptomatic treatment exists. OBJECTIVES: Based on our previous experimental model, the objective of the current study was to assess for the first time whether pulsed ultrasound (PUS) application could have beneficial effects on humans. METHODS: Prospective, double-blinded, randomized, controlled trial of 51 patients. Four were excluded, and 47 were randomized into the control group (N = 23) or PUS group (N = 24). The control group received a PUS procedure without emission, and the PUS group received 1 Mhz, 0.5 W/cm2 for 1 min/cm2. Pain level, bone callus healing rate, physical and work activity, pain medication intake, and adverse events were blindly evaluated at baseline and one, three, and six months. RESULTS: There were no significant differences at baseline between groups. PUS treatment significantly decreased pain by month 1 (P = 0.004), month 3 (P = 0.005), and month 6 (P = 0.025), significantly accelerated callus healing by month 1 (P = 0.013) and month 3 (P < 0.001), accelerated return to physical activity by month 3 (P = 0.036) and work activity (P = 0.001) by month 1, and considerably reduced pain medication intake by month 1 (P = 0.057) and month 3 (P = 0.017). No related adverse events were found in the PUS group. CONCLUSIONS: This study is the first evidence that PUS treatment is capable of improving rib fracture outcome, significantly accelerating bone callus healing, and decreasing pain, time off due to both physical activity and convalescence period, and pain medication intake. It is a safe, efficient, and low-cost therapy that may become a new treatment for patients with stable rib fractures.

Influence of sonication and in vitro evaluation of nifedipine self-nanoemulsifying drug delivery system

In order to develop a self-nanoemulsifying system, three components, olive oil, Tween 80, and Capmul, were used to construct a ternary phase diagram that helped to find the optimum formulation, which was loaded with nifedipine. The effect of sonication on drug loading was also evaluated. After that, measurement of the droplet size, size distribution, zeta potential, and scanning electron microscopy were conducted for evaluation and characterisation of the formulations. The phase diagram of four formulations showed nanosizes below 200 nm; however, only one was selected to be loaded with nifedipine. The selected formulation had the lowest droplet size of 98 nm and size distribution 0.192, and was composed of 48% Tween 80, 32% Capmul, and 20% olive oil. The nifedipine self-nanoemulsifying drug delivery system (SNEDDS) showed a significant change in the particle size (97 nm) and size distribution (0.257) after sonication. Its zeta potential was -32.3 mV indicating good stability. The SEM photographs of nifedipine showed particles with spherical shape and smooth surface. Finally, a self-nanoemulsifying formulation containing nifedipine, loaded in olive oil, was successfully prepared by mixing the oil with various types of surfactants and co-surfactants. A significant nifedipine self-nanoemulsifying system was developed and significantly improved accordingly.

Ozone Therapy Protects Against Rejection in a Lung Transplantation Model: A New Treatment?

BACKGROUND: No satisfactory treatment exists for chronic rejection (CR) after lung transplantation (LT). Our objective was to assess whether ozone (O3) treatment could ameliorate CR. METHODS: Male Sprague-Dawley inbred rats (n = 36) were randomly assigned into four groups: (1) control (n = 6), (2) sham (n = 6), (3) LT (n = 12), and (4) O3-LT (n = 12). Animals underwent left LT. O3 was rectally administered daily for 2 weeks before LT (from 20 to 50 µg) and 3 times/wk (50 µg/dose) up to 3 months. CR; acute rejection; and Hspb27, Prdx, Epas1, Gpx3, Vegfa, Sftpa1, Sftpb, Plvap, Klf2, Cldn5, Thbd, Dsip, Fmo2, and Sepp1 mRNA gene expression were determined. RESULTS: Severe CR was observed in all animals of LT group, but none of the O3-LT animals showed signs of CR, just a mild acute rejection was observed in 1 animal. A significant decrease of Hspb27, Prdx, Epas1, Gpx3, Vegfa, Sftpa1, Sftpb, Plvap, Klf2, Cldn5, Thbd, Dsip, and Fmo2 gene expression in the O3-LT group was observed CONCLUSIONS: O3 therapy significantly delayed the onset of CR regulating the expression of genes involved in its pathogenesis. No known immunosuppressive therapy has been capable of achieving similar results. From a translational point of view, O3 therapy could become a new adjuvant treatment for CR in patients undergoing LT.

A Review on the Cosmeceutical and External Applications of Nigella sativa.

It is estimated by the World Health Organization (WHO) that most of the world's population depends on herbal medicine for their health care. Nigella sativa (N. sativa), also known as black-caraway and as "Kalonji," is a well-known seed all over the world. It is one of the most common medicinal plants worldwide and contains many useful chemical constituents that we can find in its fixed oil, such as thymoquinone, thymohydroquinone, dithymoquinone, thymol, nigellicine, carvacrol, nigellimine, nigellicine, nigellidine, and alpha-hederin. Due to these numerous important ingredients it was found that it affects different areas of our body and has many pharmacological effects as antibacterial, antiviral, anti-inflammatory, and wound healing effect and also for acne vulgaris, skin cancer, pigmentation, and many cosmeceutical applications. Based on the folklore usage of N. sativa seeds and oil, they are used in various systems of food and medicines. The aim of this article is to provide a detailed survey of the literature of cosmeceutical and external applications of N. sativa which is expected to stimulate further studies on this subject.

Application of Cerium (IV) as an Oxidimetric Agent for the Determination of Ethionamide in Pharmaceutical Formulations.

Two simple methods are described for the determination of ethionamide (ETM) in bulk drug and tablets using cerium (IV) sulphate as the oxidimetric agent. In both methods, the sample solution is treated with a measured excess of cerium (IV) solution in H2SO4 medium, and after a fixed standing time, the residual oxidant is determined either by back titration with standard iron (II) solution to a ferroin end point in titrimetry or by reacting with o-dianisidine followed by measurement of the absorbance of the orange-red coloured product at 470 nm in spectrophotometry. In titrimetry, the reaction proceeded with a stoichiometry of 1 : 2 (ETM : Ce (IV)) and the amount of cerium (IV) consumed by ETM was related to the latter's amount, and the method was applicable over 1.0-8.0 mg of drug. In spectrophotometry, Beer's law was obeyed over the concentration range of 0.5-5.0 µg/mL ETM with a molar absorptivity value of 2.66 × 104 L/(mol·cm). The limits of detection (LOD) and quantification (LOQ) calculated according to ICH guidelines were 0.013 and 0.043 µg/mL, respectively. The proposed titrimetric and spectrophotometric methods were found to yield reliable results when applied to bulk drug and tablets analysis, and hence they can be applied in quality control laboratories.

Long-term study of steroid avoidance in renal transplant patients: a single-center experience.

OBJECTIVES: Steroids have played a major role in renal transplantation for more than 4 decades. However, chronic use of steroids is associated with many comorbidities. This study aimed to assess the costs and benefits of a steroid-free immunosuppression regimen in a prospective randomized controlled study of living-donor renal transplantation, which was lacking in the literature. MATERIALS AND METHODS: In our study, 428 patients were enrolled to receive tacrolimus (Tac), mycophenolic acid (MPA), basiliximab (Simulect, Novartis, Basel, Switzerland) induction and steroids only for 3 days (214 patients, study group) and steroid maintenance (214 patients, control group). Median follow-up was 66 ± 41 months. RESULTS: We found that both groups showed comparable graft and patient survival, rejection episodes, and graft function. Posttransplantation hypertension was detected in 40% of the steroid-free group and 80% of the steroid maintenance group (P = .05), whereas posttransplantation diabetes mellitus was detected in 5% and 15% of these 2 groups, respectively (P = .3). CONCLUSIONS: Among low-immunological-risk recipients of living-donor renal transplants, steroid avoidance was feasible, safe, and had less morbidity outcome using Simulect induction, then Tac and MPA as maintenance immunosuppression. Steroid avoidance was associated with a lower total cost despite comparable immunosuppression cost, which was attributed to the lower cost of associated morbidities.

Study of the risk factors and complications of diabetes mellitus after live kidney donation.

OBJECTIVES: Kidney donors, similar to the general population, are at risk for developing type 2 diabetes mellitus (T2DM). The course of donors who develop T2DM has not been well studied. This work estimates the incidence of diabetes after kidney donation, and some risk factors and complications of diabetes mellitus postdonation. MATERIALS AND METHODS: This study examined the records of 2267 donors who donated one of their kidneys between 1976 and 2014 at the Urology and Nephrology Center, Mansoura University, Egypt, and who were regularly followed up at its outpatient clinic. A total of 388 donors were included in the study, and their medical records were revised. RESULTS: Postdonation weight gain and family history of diabetes mellitus were statistically significant for the development of diabetes mellitus, high or very high albuminuria, and/or decreased creatinine clearance. Metformin and insulin use seemed to significantly reduce the protein excretion and creatinine clearance decline in the studied group. CONCLUSIONS: There is a significant impact of a family history of diabetes mellitus on the development of high or very high albuminuria and/or decreased creatinine clearance.

The preparation and evaluation of self-nanoemulsifying systems containing Swietenia oil and an examination of its anti-inflammatory effects.

There is an increasing trend among pharmaceutical industries to use natural bioactive materials as medicinal agents and to use new technologies such as self-nanoemulsifying systems. The solubility and bioavailability of poorly soluble drugs can be enhanced by self-nanoemulsifying systems. Swietenia oil is frequently used because of its antimicrobial, antimutagenic, and anticancer bioactive medical properties. This study was conducted to develop self-nanoemulsifying systems for Swietenia oil that will enhance the anti-inflammatory activity of the oil. The self-emulsifying systems developed for Swietenia oil in this study were constructed using ternary phase diagrams and contained the nonionic surfactants Labrasol(®), Tween 20, Capmul(®), and Labrafil(®). The effect of these surfactants on the formulation was examined. The mean droplet size of Swietenia oil as well as their distribution, appearance, viscosity, and spreading times were studied to find the optimum formula, which contained droplets that were less than 200 nm. The next step was to test the anti-inflammatory properties of the optimum formula using a carrageenan-induced rat paw edema test. The results from this test were compared to the oil solution. Different oil/surfactants mixtures had various emulsification properties that were related to the size of their droplets. Tween 20 is a good surfactant to use in self-emulsifying systems because it produces droplets of nano-size. Mixtures of Capmul/Labrasol at a ratio of 2:1 and Labrafil/Tween 20 at a ratio of 1:2 were able to produce self-nanoemulsifying formulations containing Swietenia oil concentrations that ranged from 20%-50%. Nanoemulsion occurred when the size of the droplets fell below 200 nm with low size distribution (<0.3) after being gently mixed with water. It was found that the hydrophilic/lipophilic balance value affected the ternary phase diagram behavior of Swietenia oil and surfactants. In addition, the anti-inflammatory properties of Swietenia oil were greater in the self-nanoemulsifying systems than in the oil solution.

Cerebral venous thrombosis. Clinical presentation and outcome in a prospective series from Sudan.

OBJECTIVE: To describe the presentation and outcome of treatment of cerebral venous thrombosis (CVT) in patients from Sudan, an example of a developing country. METHODS: In a prospective study, we described the clinical features, risk factors, and outcome of CVT in patients admitted to the National Center for Neurological Diseases, Khartoum, Sudan, the only specialized neurological hospital in the country, during the period from February 2001-October 2006. Patients were referred from other hospitals in the town or from nearby hospitals in Khartoum state. RESULTS: We recruited only adult and adolescent patients aging >/=15 years. We reviewed 15 patients (12 females and 3 males) with a mean (+/-SD) age of 33.9+/-11.8 years. Headache (n=15), papilledema (n=13), paresis (n=3), and generalized seizures (n=3) were the most common symptoms, and signs encountered. A prothrombotic risk factor was often identified (n=12). At the time of the first visit namely, 12 weeks after discharge, 7 patients (46.7%) attained complete neurological recovery, 4 (26.7%) developed optic atrophy, and 2 (13.3%) died of pulmonary embolism. CONCLUSION: The clinical features and risk factors of CVT in Sudan are not different from elsewhere, but the outcome is less favorable. Places with less privileged health service resources, late presentation or delayed accessibility to appropriate diagnostic tools may negatively influence the final outcome.

Effects of certain antibilharzial and contraceptive drugs on liver functions in rats.

Effects of single and combined administration of contraceptive drug (microvlar-30) and anti-urinary bilharzial drug (metriphonate) as well as anti-intestinal bilharzial drug (oxamniquine) on the liver functions of female albino rats were studied. Metriphonate increased serum globulin content and caused no change in the hepatic cells. Oxamniquine significantly increased the activities of serum transaminases and alkaline phosphatase and caused necrosis in some liver cells. Microvlar-30 exhibited no change on the serum enzymes, while marked increase was found in serum triglyceride and protein levels. The combined administration of metriphonate or oxamniquine with microvlar-30 prevented the increase in the levels of serum triglycerides and proteins. Histopathological examination confirmed the results obtained by chemical analysis.
