Plant secondary metabolites, present in the outer layers of fruits and vegetables in higher amounts, are structurally diverse and comprise different classes of phyto-constituents that have a number of health-promoting properties. Blanching is an important pre-treatment that is used to inactivate the enzymatic oxidation. Methods: This study was designed to investigate the effects of steam blanching (3, 5 and 7 min) and drying (50ºC) of custard apple (Annona squamosa) peel on the quantification of secondary metabolites and hypo-glycemic activity. Unblanched sample dried at 50ºC served as control. Quantitative tests for alkaloids, tannins, saponins and flavonoids were carried out for all samples and in vitro alpha amylase inhibition test was done to confirm the hypo-glycemic properties. All analyses were done in triplicates. Results: Quantitative results for alkaloids, tannins, saponins showed a significant reduction (p<0.05) as the blanching time increased, whereas for the unblanched sample, it was not statistically significant (p>0.05). The exception was observed in the flavonoid content which showed a significant increase for 3 min and 5 min blanched samples, while the 7 min blanched sample showed a reduction in flavonoid content over the unblanched and fresh samples. Alpha amylase inhibition test similarly showed a decreasing trend for blanched samples ranging from IC50 value of 3.31 to 5.53 μg/mL compared to the unblanched with IC50 value of 4.92 μg/mL and fresh sample with IC50 value of 6.37μg/mL. Conclusion: From the study, it is inferred that steam blanching and drying have a significant impact on the quantification of secondary metabolites and subsequently on its hypo-glycemic activity. A steam blanching time of 5 min is the optimum for processing of custard apple peel.

The objectives of this hospital based cross-sectional study were to evaluate the socio-demographic profile, manner of death and histopathological changes in the lungs, liver and kidneys of individuals who died of pesticide poisoning. All fatal cases of pesticide poisoning from February 2011 to January 2012 were evaluated. Socio-demographic profile, type of exposure and manner of death were recorded for each of the cases. Autopsy was performed with detailed internal and external examinations. Random portion of Lung, Liver and Kidney were collected and fixed in 10.0% Formalin. Hematoxylin and Eosin stained sections were examined and findings recorded. The total number of deaths due to fatal pesticide poisoning was 9.6%. Highest frequency of poisoning (23.4%) was seen in the age group 20 - 29 years. The peak time of consumption of poisoning was between 6.00am and 12.00noon. The manner of poisoning was suicidal in majority of the cases. Histological findings indicated that congestion was the most common histopathological change; being observed in 60.0%, 66.0% and 74.0% of cases of liver, lung and kidney respectively. Histopathological features are supportive in establishing the diagnosis but further studies with larger sample size may be more illuminative in explaining the histopathological changes occurring due to these chemicals.

Recurrent aphthous stomatits (RAS) is also known as recurrent oral ulcers, recurrent aphthous ulcers, or simple or complex aphthosis. RAS is the most common inflammatory ulcerative condition of the oral mucosa in North American patients. RAS has been the subject of active investigation along multiple lines of research including epidemiology, immunology, clinical correlations and therapy. Clinical evaluation of the patient requires correct diagnosis of RAS and classification of the disease based on morphology (MIAU, MJAU, HU) and severity (simple versus complex). In order to properly diagnose and treat a patient with lesions of RAS, the clinician must exclude other causes of acute oral ulcers. Complex aphthosis and complex aphthosis variants associated with systemic disorders should be considered. The aphthous-like oral ulcerations of patients with HIV disease represent a challenging differential diagnosis. The association of lesions of RAS with hematinic deficiencies and gastrointestinal diseases provides an opportunity to identify a "correctable cause" which, with appropriate treatment, can result in a remission or substantial lessening of disease activity. Finally, when all of these factors are considered, the evaluation of the patient for Behcet's disease can be continued on firm grounds that one of the major criteria for the diagnosis of Behcet's disease has been met.

Objective: To investigate hepatoprotective activity of the methanolic extract of Fagonia indica Burm. on CCl4 induced hepatotoxicity in albino rats. Methods: Animals in Group 1 served as vehicle control, Group 2 served as hepatotoxin (CCl4 2ml/kg, s.c) treated group, Group 3 served as standard (Silymarin 50mg/kg, p.o.) treated group. Group4 and 5 served as methanolic extract of Fagonia indica (MEFI) in different doses (200 mg/kg and 400 mg/kg b.w., p.o).The degree of protection was determined by measuring levels of biochemical marker like SGOT, SGPT, ALP, Bilirubin (Total & Direct) and Cholesterol. The histopathological studies also show the hepatic protection of the test extracts. Results: The levels of the biochemical parameters such as SGPT, SGOT, ALP, Total bilirubin, Direct bilirubin and Cholesterol were significantly increased in CCl4 treated rats when compared with the normal group (P<0.05), but the MEFI (400 mg/kg, bw) treated rats showed maximum reduction of SGOT (114.83±1.51), SGPT (164.33±1.25), ALP (154.83±1.53), Total bilirubin (1.55±0.01), Direct bilirubin (0.65±0.009) and Cholesterol (193.00±1.06) in a significant manner. Histopathological studies also reveal the hepatoprotection property of MEFI in a dose dependent manner. Conclusions: These results suggest that MEFI in different doses showed significant hepatoprotective activity against CCl4 induced hepatotoxicity and this might be due to the presence of flavonoids and tannins. Further research is sought to explore the exact mechanism of action and phytoconstituents responsible for the pharmacological response.

AIMIn the present study, a variety of high resolution microscopy techniques were used to visualize the organization and motion of lipids and proteins in the sperm's plasma membrane. We have addressed questions such as the presence of diffusion barriers, confinement of molecules to specific surface domains, polarized diffusion and the role of cholesterol in regulating lipid rafts and signal transduction during capacitation.

METHODSAtomic force microscopy identified a novel region (EqSS) within the equatorial segment of bovine, porcine and ovine spermatozoa that was enriched in constitutively phosphorylated proteins. The EqSS was assembled during epididymal maturation. Fluorescence imaging techniques were then used to follow molecular diffusion on the sperm head.

RESULTSSingle lipid molecules were freely exchangeable throughout the plasma membrane and showed no evidence for confinement within domains. Large lipid aggregates, however, did not cross over the boundary between the post-acrosome and equatorial segment suggesting the presence of a molecular filter between these two domains.

CONCLUSIONA small reduction in membrane cholesterol enlarges or increases lipid rafts concomitant with phosphorylation of intracellular proteins. Excessive removal of cholesterol, however, disorganizes rafts with a cessation of phosphorylation. These techniques are forcing a revision of long-held views on how lipids and proteins in sperm membranes are assembled into larger complexes that mediate recognition and fusion with the egg.

The animal model deals with the species other than the human, as it can imitate the disease progression, its’ diagnosis as well as a treatment similar to human. Discovery of a drug and/or component, equipment, their toxicological studies, dose, side effects are in vivo studied for future use in humans considering its’ ethical issues. Here lies the importance of the animal model for its enormous use in biomedical research. Animal models have many facets that mimic various disease conditions in humans like systemic autoimmune diseases, rheumatoid arthritis, epilepsy, Alzheimer’s disease, cardiovascular diseases, Atherosclerosis, diabetes, etc., and many more. Besides, the model has tremendous importance in drug development, development of medical devices, tissue engineering, wound healing, and bone and cartilage regeneration studies, as a model in vascular surgeries as well as the model for vertebral disc regeneration surgery. Though, all the models have some advantages as well as challenges, but, present review has emphasized the importance of various small and large animal models in pharmaceutical drug development, transgenic animal models, models for medical device developments, studies for various human diseases, bone and cartilage regeneration model, diabetic and burn wound model as well as surgical models like vascular surgeries and surgeries for intervertebral disc degeneration considering all the ethical issues of that specific animal model. Despite, the process of using the animal model has facilitated researchers to carry out the researches that would have been impossible to accomplish in human considering the ethical prohibitions.

PURPOSE: To report transient corneal edema after phacoemulsification as a predictive factor for the development of pseudophakic cystoid macular edema (PCME). METHODS: A total of 150 eyes from 150 patients (59 men and 91 women; mean age, 68.0 ± 10.15 years) were analyzed using spectral domain optical coherence tomography 1 week and 5 weeks after routine phacoemulsification cataract surgery. Transient corneal edema detected 1 week after surgery was analyzed to reveal any significant relationship with the development of PCME 5 weeks after surgery. RESULTS: Transient corneal edema developed in 17 (11.3%) of 150 eyes 1 week after surgery. A history of diabetes mellitus was significantly associated with development of transient corneal edema (odds ratio [OR], 4.04; 95% confidence interval [CI], 1.41 to 11.54; p = 0.011). Both diabetes mellitus and transient corneal edema were significantly associated with PCME development 5 weeks after surgery (OR, 4.58; 95% CI, 1.56 to 13.43; p = 0.007; and OR, 6.71; CI, 2.05 to 21.95; p = 0.003, respectively). In the 8 eyes with both diabetes mellitus and transient corneal edema, 4 (50%) developed PCME 5 weeks after surgery. CONCLUSIONS: Transient corneal edema detected 1 week after routine cataract surgery is a predictive factor for development of PCME. Close postoperative observation and intervention is recommended in patients with transient corneal edema.

A pig was confirmed to be a true hermaphrodite on the basis of gross and histomorphological studies of the genital organs. The genitalia was consisted of left ovary, oviduct, two coiled uterine horns, body of uterus alongwith right testis and an epididymis. Vagina and vulva were absent but male urethra with prostate gland was present. Grossly the size of all the genital organs appeared to be normal. Histomorphologically, testis and epididymis were underdeveloped as there was no clearcut spermatogenia and sertoli cells but Leydig cells were normal. The ovary presents normal histological features with some portion of testicular tissue. Degeneration of uterine epithelium was observed along with normal endometrial glands.

Umbilical cord ulceration is a rare condition presenting with sudden fetal bradycardia due to fetal hemorrhage and in most cases leading to intrauterine death. A strong association with intestinal atresia has been reported. Most cases present after 30 weeks of gestation, with preterm labor or rupture of membranes followed by sudden fetal bradycardia. We report two such cases of umbilical cord ulceration and review the available literature. One of the cases interestingly presented at 26 weeks, much earlier than what is reported in the world literature. In view of high perinatal mortality and morbidity, awareness of this condition is mandatory for timely and appropriate management to improve the fetal outcome.
