Aquatic systems are major reservoirs of antibiotic resistance genes in the environment. In this study, we have isolated the antibiotic resistance bacteria from aquatic systems including river Ravi, fish farm and underground drinking water source. Physical, chemical and microbiological parameters were studied, bacteria were isolated, gram staining and genus identification was done by following the Burgey’s manual of systematic bacteriology. While, antibiotic susceptibility testing was done by following the disk diffusion method and CLSI guidelines. Multiple antibiotic resistant indexes were calculated. There was no significant discrepancy in physical and chemical parameters of water samples whereas in microbiological parameters, a variable number of bacteria were found in all 3 water samples indicating the presence of microbial contamination. A total of 33 bacterial strains were identified including Enterobacteriaceae, Pseudomonas, Bacillus, Lactobacillus and Staphylococcus species. Out of 10 classes of antibiotics, resistant against 8 classes were identified. Organisms isolated from river Ravi were the most resistant isolates. Most of the organisms were resistant to Penicillins, Carbapenems and Cephalosporins. MAR index of isolated strains ranges from 0.43 to 0.88.

The current research was aimed to assess the physicochemical characteristics, polyphenols and antioxidants of S. cumini seed. The physical characteristics such as the color of S. cumini seed were white to pink, the shapes resembled to oblong and coarse texture. The length, width and weight of fresh S. cumini seed were found to be (18.20±0.81mm, 11.05±0.41mm and 1.80±0.16g), respectively while the color of dried S. cumini seeds were light brown to brown,rhombus in shape with loutish texture. The average length, width and weight of dried S. cumini seeds were 16.47±0.45; 10.14±0.25 mm and 0.75±0.12 g respectively. S. cumini seeds powder were evaluated for their chemical composition e.g. carbohydrate, protein, fat, crude fiber, moisture content and ash (77.27±2.50, 3.62±0.30, 6.25±0.55, 10.30±1.20 and 1.55±0.11 g/100g), respectively. Quantitative analysis of total phenolic content was performed it was found that the methanolic and water extract had 52±1.65 and 40±1.25 mg GAE/g content. Free radical scavenging activity was also evaluated to estimate the antioxidant property of extract. Among tested extracts maximum % inhibition 96.61±1.90% was found in methanol extract and 69.30±1.56% in water extract, while BHT has % inhibition 50.70±1.32% at concentration 100 μg/ml.

The most obvious sign of Alzheimer’s is dementia which is primarily an affliction of old age. Majority of the people presenting with dementia in old age are Alzheimer’s patients. The symptoms of Alzheimer’s disease are debilitating and have the ability to utterly disrupt a person's normal life. It is only discovered after this terrible disease has destroyed all neurons, thus there is little chance to cure it or reverse the adverse effects. There are two types of techniques for detecting Alzheimer's disease: invasive and non-invasive techniques. Invasive method obtains data from the patient bydrawing a small amount of blood or performing a lumbar puncture, whereas noninvasive method collects data using imaging techniques like MRI and CT scan. Invasive technique, on the other hand, is thought to be a more accurate indicator of Alzheimer's disease than non-invasive technique since it provides strong biomarkers. Once Alzheimer's disease has progressed to its final stage, it is incurable. Treatment is only viable when the disease is in its initial stages. Future treatments for Alzheimer's disease will focus on the causative maladies of neurofibrillary tangles (ptau) and senile plaques (A).

Bacteria were also screened for biosurfactant, indole 3-acetic acid production, phosphate solubilization, and antifungal bioassay. Microbacterium schleiferi and Bacillus subtilis were able to grow at 2% diesel oil concentration and exhibited plant growth promoting activities. Green house analysis revealed that augmentation with biosurfactant producing and plant growth promoting bacteria enhanced the plant growth and diesel oil degradation (80%) as compared to the treatments in which bacteria and plants were separately used.

The purpose of the study was to find the prevalence of congenital cataract in children. About 100 cases of congenital cataract including both male and female children were identified from age group of 1-13years. Congenital cataract was diagnosed using Snellen’s visual acuity test, ophthalmoscope and slit lamp test. Male children showed greater prevalence of congenital cataract as compared to female children. The prevalence of congenital cataract in male children was 55% (n=55) while among female children, it was 45% (n=45). Both conditions of unilateral and bilateral congenital cataract were observed with incidence of 46% (n=46) and 54% (n=54) in male and female children respectively. Lens extraction was also done in 94% (n=94) and after surgery 55% (n=52) patients showed positive response and 45% (n=42) patient had negative response for light perception.

Proper phenotypic data supported by genetic evidence is crucial for every type of specimen keeping in view its significance. Several methods of species identification both morphological and genetic are being used. DNA barcoding using a fragment of cytochrome c oxidase subunit I (COI) mitochondrial gene is gaining popularity because of its accuracy and efficiency. In this study, six type specimens of endemic fishes from Pakistan preserved at Stephenson Natural History Museum, GC University, Lahore, Pakistan were analyzed for their genetic diversity from other members of the genus. COI barcode sequences of Clupisoma naziri, Barilius vagra pakistanicus, Nemacheilus naziri, Nemacheilus griffithi hazarensis, Schizothorax skarduensis, and Naziritor zhobensis were obtained and analyzed. The obtained sequences were approximately 655bp long. The average Kimura-twoparameter( K2P) distances from other members of genera were 0.608%, 0.44%, 0.42%, 0.608%, 0.945%, and 1.364% for Clupisoma naziri, Barilius vagra pakistanicus, Nemacheilus naziri, Nemacheilus griffithi hazarensis, Schizothorax skarduensis, and Naziritor zhobensis respectively.
