ABSTRACT

In recent years, there has been a growing interest in development of a diverse range of foods that are enriched with omega-3 fatty acids. It is widely recognized that through dietary interventions, the lipid fraction of food can be modified to enhance its nutritional content. This study is aimed to develop chicken patties enriched with poly unstaurated fatty acids (PUFAs) extracted from microalgae aurintricarboxylic acid (ATA) concentration of 0% (T0), 1% (T1), 2% (T2), and 3% (T3). All treatments were stored at -18 °C for one month and analysed at an interval of 0, 10, 20, and 30 days to assess the effect of PUFAs supplementation on physicochemical, oxidative, microbiological and organoleptic properties of chicken patties. The results revealed that moisture content was significantly increased during the storage; the maximum moisture was observed in T0 (67.25% ± 0.03) on day 0, while the minimun was found in T3 (64.69% ± 0.04) on day 30. Supplemenatation of PUFAs in chicken patties significantly enhanced the fat content of the product the highest fat content was observed for T3 (9.7% ± 0.06. An increase in PUFAs concentration led to a significant increase in thiobarbituric acid reactive substances (TBARS). TBARS were increased from 1.22 ± 0.43 at 0 days to 1.48 ± 0.39 at 30 days of storage. The PUFAs incorporation negatively effected sensory acceptance of the product ranging from (8.41 ± 0.17 to 7.28 ± 0.12). However, the sensory scores were in acceptable range for supplemented patties as compared to control sample. Treatment T3 depicted the highest nutritional content. The sensory and physiochemical analysis of supplemented patties suggested that PUFAs extracted from microalgae can be used as a functional ingredient in the preparation various meat products particularly chicken meta patties. However, antioxidants should be added to to prevent lipid oxidation in the product.

ABSTRACT

YABBY is among the specific transcription factor (TF) gene family in plants and plays an important role in the development of the leaves and floral organs. Its specific roles include lateral organ development, the establishment of dorsoventral polarity, and response to abiotic stress. Potato is an important crop worldwide and YABBY genes are not still identified and characterized in potato. So, little has been known about YABBY genes in potato until now. This study was carried out to perform genome-wide analysis, which will provide an in-depth analysis about the role of YABBY genes in potato. There have been seven StYAB genes identified, which are found to be located on seven different chromosomes. Through multiple sequence analyses, it has been predicted that the YABBY domain was present in all seven genes while the C2-C2 domain was found to be absent only in StYAB2. With the help of cis-element analysis, the involvement of StYAB genes in light, stress developmental, and hormonal responsiveness has been found. Furthermore, expression analysis from RNA-seq data of different potato organs indicated that all StYAB genes have a role in the vegetative growth of the potato plant. In addition to this, RNA-seq data also identified StYAB3, StYAB5, and StYAB7 genes showing expression during cadmium, and drought stress, while StYAB6 was highly expressed during a viral attack. Moreover, during the attack of Phytophthora infestans on a potato plant StYAB3, StYAB5, StYAB6, and StYAB7 showed high expression. This study provides significant knowledge about the StYAB gene structures and functions, which can later be used for gene cloning, and functional analysis; this information may be utilized by molecular biologists and plant breeders for the development of new potato lines.

ABSTRACT

Banana peel powder is considered one of the most nutritive and effective waste product to be utilized as a functional additive in the food industry. This study aimed to determine the impact of banana peel powder at concentrations of 2%, 4%, and 6% on the nutritional composition, physicochemical parameters, antioxidant potential, cooking properties, microbial count, and organoleptic properties of functional nuggets during storage at refrigeration temperature for 21 days. Results showed a significant increase in nutritional content including ash and crude fiber ranging from 2.52 ± 0.017% to 6.45 ± 0.01% and 0.51 ± 0.01% to 2.13 ± 0.01%, respectively, whereas a significant decrease was observed in crude protein and crude fat ranging from 13.71 ± 0.02% to 8.92 ± 0.02% and 9.25 ± 0.02% to 4.51 ± 0.01%, respectively. The incorporation of banana peel powder significantly improved the Water Holding Capacity from 5.17% to 8.37%, cooking yield from 83.20 ± 0.20% to 87.73 ± 0.16% and cooking loss from 20.19 ± 0.290% to 13.98 ± 0.15%. Antioxidant potential was significantly improved as TPC of functional nuggets increased ranging from 3.73 ± 0.02 mg GAE/g to 8.53 ± 0.02 mg GAE/g while a decrease in TBARS (0.18 ± 0.02 mg malonaldehyde/kg to 0.14 ± 0.02 mg malonaldehyde/kg) was observed. Furthermore, functional broiler nuggets depicted a significantly reduced total plate count (3.06-4.20 × 105 CFU/g) than control, which is likely due to high amounts of phenolic compounds in BPP. Broiler nuggets supplemented with 2% BPP (T1) received the greatest sensory scores in terms of flavour, tenderness, and juiciness. Results of current study revealed the potential of BPP to be utilized as an effective natural source of fibre supplementation in food products along with enhanced antioxidant and anti-microbial properties.

ABSTRACT

Climate change, pesticide resistance, and the need for developing new plant varieties have galvanized biotechnologists to find new solutions in order to produce transgenic plants. Over the last decade scientists are working on green metallic nanoparticles to develop DNA delivery systems for plants. In the current study, green Iron nanoparticles were synthesized using leaf extract of Camellia sinensis (green tea) and Iron Chloride (FeCl3), the characterization and Confirmation was done using UV-VIS Spectroscopy, FTIR, SEM, and TEM. Using these nanoparticles, a novel method of gene transformation in okra plants was developed, with a combination of different Magnetofection factors. Maximum gene transformation efficiency was observed at the DNA to Iron-nanoparticles ratio of 1:20, by rotation of mixture (Plasmid DNA, Iron-nanoparticles, and seed embryo) at 800 rpm for 5 h. Using this approach, the transformation of the GFP (green fluorescent protein) gene was successfully carried out in Abelmoschus esculentus (Okra plant). The DNA transformation was confirmed by observing the expression of transgene GFP via Laser Scanning Confocal Microscope (LSCM) and PCR. This method is highly economical, adaptable, genotype independent, eco-friendly, and time-saving as well. We infer that this approach can be a potential solution to combat the yield and immunity challenges of plants against pathogens.

ABSTRACT

The current research project involves isolation and characterization of PSM (phosphate solubilizing microorganisms) from the rhizospheric soil of certain medicinal plants and to determine their effect on plant growth. Medicinal plants, Aloe vera, Bauhinia variegata, Cannabis sativa, Lantana camara and Mentha viridis were selected for the isolation of PSMs. Soil status of the selected medicinal plants was also checked. Phosphate solubilizing bacteria (PSB) were observed under stereomicroscope for their morphological characteristics and Gram's staining. Phosphate solubilizing fungi (PSF) were also identified microscopically. Colony diameter, halo zone diameter and solubilization index were determined on PVK agar plates. TLC results indicated that citric acid was the most common acid produced by PSM strains. All strains were found to be non-pathogenic in pathogenicity test. A positive plant growth response to PSM inoculation was observed in all studies. In study 1, individual inoculation of PSM showed a significant increased effect on plant growth parameter i.e., fresh and dry weight, plant height and root and shoot length as compared to control. In study2, composite inoculation of PSM along with different P sources revealed that rock phosphate (RP) with PSM increased growth of plants significantly. The present study suggests that PSM inoculation along with RP amendment can be used as biofertilizer.

ABSTRACT

Herbal drugs play an imperative role in healthcare programs in developing countries. Curry leaves have wide medicinal importance and are used to treat various diseases traditionally. The current study was carried out to estimate the extent of mercury toxicity and the potential effect of curry leaves against defined toxicity. The study group comprised 24 rats weighing between 130 and150 g. Group 1 was kept normal, and group 2 was exposed to mercury at 0.4 mg/kg of body weight in the form of mercuric chloride (HgCl2). The group 3 animals were treated with curry leaves with a dosage of 300 mg/kg of body weight. Group 4 was treated with curry leaves along with mercury with a dosage of 300 and 0.4 mg/kg consecutively. After 28 days, the rats were killed. Blood sample of all groups were evaluated separately to determine the results of different parameters. The results show that ALP, AST, ALT, urea, bilirubin, and creatinine increased with mercury application and decreased with curry leaf exposure. SOD, CAT, GPx, and GR of the liver as well as the kidney depleted on mercury exposure whereas they increased with curry leaf application. HDL increased with curry leaf application and decreased with mercury treatment, while LDL, triglyceride, and cholesterol decreased with curry leaves and increased with mercury exposure. Organ index in mercury along with curry leaf application got close to normal.

ABSTRACT

Neonatal severe hyperparathyroidism (NSHPT) is a rare genetic disorder that presents within the first six months of life. We present the case report of a male child who presented to us in the first month of his life with symptoms of lethargy, constipation, and reluctance to feed. One sibling of the child had died earlier with similar symptoms in the first six months of life. Upon physical examination, the child was lethargic, dehydrated, had bradycardia with hyperreflexia. Serum electrolyte analysis showed hypercalcaemia and hypophosphataemia. Further workup revealed elevated serum parathyroid hormone levels and Calcium sensing receptor (CaSR) gene mutation in autosomal recessive patterns. The father was discovered to be heterozygous for the same mutation but is asymptomatic. Diagnosis of neonatal severe hyperparathyroidism was made and the child was managed medically with intravenous fluids, Furosemide, Pamidronate, and Cinacalcet. On inconsistent response to medical therapy, he underwent total parathyroidectomy with auto transplantation of half of the left lower parathyroid gland. Postoperatively, the child is being managed on oral calcium and Alpha Calcidiol supplementation and is doing well.

ABSTRACT

Pectinases hydrolyze pectin and make up 25% of global food processing enzyme sales. In this study, we aimed to purify exo-polygalacturonase (Exo-PG) by using galacturonic acid conjugated magnetic nanoparticles (MNPs) and examined its application in juice purification. The submerged fermentation was carried out in the presence of apple pectin (1%) to promote production of exo-PG from Aspergillus flavus. Maximum exo-PG activity was observed after 4 days (30 °C and pH 5.0). A single protein band (66 kDa) of purified exo-PG was observed in SDS-PAGE. Purification of exo-PG enzyme was âˆ¼ 10 fold with a yield of 29%. The enzyme retained 98% activity in the presence of 15 % glycerol at 4 °C. The purified exo-PG using MNPs yielded a 10-12% increase in juice production as compare to without treated fruit juice. To the best of our knowledge, this is the first report of affinity purification of exo-PG enzyme, using engineered magnetic nanoparticles.

ABSTRACT

Rheumatoid arthritis is an autoimmune disorder causing joint deformity and work disability. Several drugs are available to deal with the disease including conventional drugs; biological drugs such as TNFα inhibitors, B cell-targeted drugs, T cell co-stimulation inhibitors, interleukin-6 inhibitors, and interleukin-1 inhibitors; and kinase inhibitory drugs. In spite of the broad spectrum of drugs available, the disease remains uncontrolled in a number of patients and there is a need for new drugs with better efficacy and universal response rate. The failure of the available drugs to control the disease can be owed to the complex pathogenesis with complementary pathways of disease progression. The blockade of one pathway cannot supersede pathogenesis through other complementary pathways. Janus kinase (JAK) and Bruton's tyrosine kinase (BTK) are the two important mediators of disease which control a number of signaling pathways involved in rheumatoid arthritis pathogenesis. In this study, using the computer-aided drug designing techniques (virtual screening, molecular docking, and molecular dynamics studies), we have designed piperidinyl dipyrrolopyridine-based dual inhibitors of Janus kinase and Bruton's tyrosine kinase. Dual JAK and BTK inhibitors seem promising to fight the complex pathogenesis of the disease at multiple fronts and can be the future drug for patients unresponsive to current remedies.

ABSTRACT

In present study hypoglycaemic effects of the crude powdered C. decussata and its methanolic extract (ME) in alloxan diabetic rabbits were evaluated. The hypoglycaemic effect was measured by blood glucose, insulin level, HbA1c and his to pathology of pancreas. Glucose lowering effect of the ME was studied in diabetic rabbits. The effects of extract on blood glucose, body weight, food in take, fluid intake, OGTT were also evaluated. The results showed that 0.5,1 and 2g/kg of the powder significantly decreased blood glucose levels in normal rabbits and diabetic rabbits at the intervals checked. Oral intake of pioglitazone also reduced the levels in these rabbits. Synergistic hypoglycaemic effect of 600mg/kg of ME with different doses of insulin (2 & 3unit/kg, s/c) further reduced blood glucose levels of treated alloxan-diabetic rabbits. The oral glucose tolerance test revealed lowered area under curve values in ME treated rabbits. Treatment with ME (400 and 600 mg/kg) for 30 days showed highly significant decrease in blood glucose level by augmenting insulin secretion, HbA1cand significant increase in body weight, serum insulin levels in treated diabetic rabbits. Histopathology study showed regeneration of ß-cells. These studies have, therefore, supported the traditional use of this herb in diabetic patients.

ABSTRACT

OBJECTIVE: To compare the outcome of submucosal resection of nasal septum under local and general anaesthesia. METHODS: The retrospective study was conducted at the Sindh Government Hospital, Korangi, Karachi, from November 2008 to June 2010. A total of 100 patients (50 male and 50 females) having unilateral or bilateral nasal obstruction with moderate deviation of the nasal septum and unilateral or bilateral inferior turbinate hypertrophy, undergoing surgical treatment were inducted. They were divided into two groups: 50 patients of either gender operated under local anaesthesia; and the rest who were operated under general anaesthesia. All these patient came for post-operative follow up in July and August 2010, and both groups were compared. SPSS 18 was used for statistical analysis. RESULTS: Of the 100 patients, there were 19 complications: 1 (5.26%) among those who had undergone local anaesthesia, and 18 (94.73%) among those who had been given general anaesthesia. Besides, in Group I, the cost of the drugs averaged Rs500 per patient, the average time consumed was 20 minutes, and bleeding at time of surgery was mild (10 to 15 ml). In Group II, the average cost of drug Rs1500 per patient, the average time consumed was 40 minutes, and bleeding at time of surgery was moderate (15 to 100ml). No mortality was seen in either group. CONCLUSION: Local anaesthesia was found to be a far more safe, effective and economical option for submucosal resection of nasal septum.
