Plant stress reduction research has advanced significantly with the use of Artificial Intelligence (AI) techniques, such as machine learning and deep learning. This is a significant step toward sustainable agriculture. Innovative insights into the physiological responses of plants mostly crops to drought stress have been revealed through the use of complex algorithms like gradient boosting, support vector machines (SVM), recurrent neural network (RNN), and long short-term memory (LSTM), combined with a thorough examination of the TYRKC and RBR-E3 domains in stress-associated signaling proteins across a range of crop species.

The lack of local availability for drugs in the colon can be addressed by preparing a self-microemulsifying drug delivery system (SMEDDS) of curcumin (Cur) which is ultimately used for the treatment of inflammatory bowel disease (IBD). From preformulation studies, Lauroglycol FCC (oil), Tween 80 (surfactant), Transcutol HP (co-surfactant), and Avicel (solid carrier) were selected for the preparation of blank liquid and solid Cur-loaded SMEDDSs (S-Cur-SMEDDSs).

Article Synopsis
  • - Pathogenic variants in the APC gene are responsible for familial adenomatous polyposis, the most common hereditary gastrointestinal polyposis syndrome, prompting the development of specific classification criteria to aid in variant interpretation.
  • - The study involved applying these APC-specific criteria to assess over 10,000 unique APC variants from databases like ClinVar and LOVD, leading to a significant reclassification of variants of uncertain significance (VUSs), with many being reassessed as (likely) benign or (likely) pathogenic.
  • - The results showed that using these tailored criteria effectively reduced VUSs by 37%, highlighted the potential for systematic variant classification in large datasets, and established a model that could benefit future genetic variant interpretation efforts in

Article Synopsis
  • The genetic factors contributing to stroke risk in South Asians remain largely unstudied, with a recent study examining 75,000 Pakistanis using exome-wide sequencing.
  • A specific genetic variant, NOTCH3 p.Arg1231Cys, was found to be more common in South Asians (0.58%) compared to Western Europeans (0.019%) and was significantly linked to hemorrhagic and overall stroke risk.
  • This variant accounts for about 2.0% of hemorrhagic strokes and 1.1% of all strokes in South Asians, emphasizing the importance of including diverse populations in genetic research for better understanding and treatment of stroke.

Continuous use of oral NSAIDs can damage mucosal membrane, which results in decreased bioavailability and non-compliance with the therapy. But the use of sustained release drug delivery systems might offer a solution. Objective was to synthesize mucoadhesive SR microspheres by using different combinations of pectin (PEC) and its thiolated derivative (T-PEC3100) for improved loxoprofen (LS) permeation.

Omeprazole, a drug of choice for the management of gastric hyperacidity, influences serotonergic neurotransmission in brain regions and its long-term use is known to cause stress-related behavioral deficits including anxiety. Aim of the current study was to explore the effects of omeprazole treatment on immobilization-induced anxiety in rats, specifically on the role of serotonin (5-HT). In view of the role of serotonin-1A (5-HT1A) autoreceptor in the availability of 5-HT in brain regions, mRNA expression of this autoreceptor was performed in raphe nuclei.

Objective: The aim of our study was to investigate the relationship between clinical indicators and gene dysregulation in different types of epilepsy, while also seeking to identify a diagnostic model capable of distinguishing between focal and generalized seizures. This highlights the critical importance of understanding clinical indicators and gene dysregulation for targeted therapeutic interventions to effectively address the specific seizure types effectively.

Materials And Methods: In this study, we conducted a comprehensive analysis of the peripheral blood of epilepsy patients (n = 100) and a control group (n = 51) to determine the differential gene expression.

Article Synopsis
  • Colorectal cancers (CRCs) linked to biallelic germline variants show specific mutational signatures (SBS18+SBS36 and SBS30) that could also be present in adenomas, which are precursors to CRCs.
  • A study sequenced DNA from adenomas and CRCs in biallelic cases and compared them with sporadic cases to investigate these signatures.
  • Results indicated that adenomas in biallelic cases had similar mutational signature proportions as their corresponding CRCs, suggesting testing adenomas could enhance the detection of biallelic cases and improve variant classification for better CRC prevention strategies.

Background And Aim: The present study aimed to evaluate and compare the overall and breed-specific seasonal breeding patterns, fertility rates, cyclicity, and follicular dynamics of Arab, Thoroughbred, and Percheron mares under the subtropical conditions of Pakistan.

Materials And Methods: A retrospective analysis of climatic data and breeding records of eleven breeding studs spanning four years (2020-2023) was made to find out the overall seasonality in the breeding pattern of mares. Fifty mares of each breed (n = 150 in total) were scanned by ultrasonography for a calendar year to find the cyclicity pattern and follicular dynamics (follicular growth rate, size of ovulatory follicle, and days from estrus till ovulation).

Diarrhea is a globally major problem especially Escherichia coli induced diarrhea becoming fatal nowadays in developing countries. Colon-targeted chitosan microspheres (Ms) comprising of lipase‑zinc and lipase‑copper complexes were prepared, loaded with Attapulgite (Cts-Li-Zn-ATG/Ms and Cts-Li-Cu-ATG/Ms) for the treatment of bacterial diarrhea. Thin layer chromatography (TLC) and Fourier-transform infrared spectroscopy (FTIR) studies were used for confirmation of proposed lipase-metal complexes.

Introduction: Ureteric stones, characterised by their presence in the ureter, present a common yet often painful urological condition requiring timely intervention. As C-reactive protein (CRP) emerges as a potential biomarker, its correlation with the spontaneous stone passage (SSP) offers valuable insights into patient management and treatment strategies. The present study aimed to assess if CRP levels can predict SSP in symptomatic lower ureteric calculi of size 5 mm-10 mm.

The integration of target capture systems with next-generation sequencing has emerged as an efficient tool for exploring specific genetic regions with a high resolution and facilitating the rapid discovery of novel alleles. Despite these advancements, the application of targeted sequencing methodologies, such as the myBaits technology, in polyploid oat species remains relatively unexplored. In this study, we utilized the myBaits target capture method offered by Daicel Arbor Biosciences to detect variants and assess their reliability for variant detection in oat genomics and breeding.
