Tomato yellow leaf curl virus-Oman (TYLCV-OM),  a variant of the Tomato yellow leaf curl virus-Iran (TYLCV-IR) strain, was identified in 2005 as the cause of tomato yellow leaf curl disease (TYLCD) in Oman and is  associated with a betasatellite namely as Tomato leaf curl betasatellite (ToLCB). Surveys were carried out from three diverse Governorates of Oman to investigate the correlation between the betasatellite and the virus. The visual assessment and scoring of infected tomato plants in the field revealed that the association of betasatellite with the disease was highest in Sharqia at 77%, followed by Dakhlia at41% and lowest in Batinah at30% .

Article Synopsis
  • Evidence-based bundles for inserting and maintaining central lines significantly lower the rates of CLABSI in ICUs.
  • Researchers examined how well these prevention programs were adopted and followed in ICUs across a large network of Canadian hospitals.
  • The study focused on the relationship between compliance with these bundles and actual CLABSI rates.

Flexible thermoelectric materials are usually fabricated by incorporating conducting or organic polymers; however, it remains a formidable task to achieve high thermoelectric properties comparable to those of their inorganic counterparts. Here, we present a high zT value of 1.29 ± 0.

Understanding the role of the mitogen-activated protein kinases (MAPKs) signalling pathway is essential in advancing treatments for neurodegenerative disorders like Alzheimer's. In this study, we investigate in-silico techniques involving computer-based methods to extract the MAPK1 sequence. Our applied methods enable us to analyze the protein's structure, evaluate its properties, establish its evolutionary relationships, and assess its prevalence in populations.

Article Synopsis
  • The study investigates the impact of sentinel lymph node biopsy (SLNB) on outcomes in older women (≥ 70 years) with early-stage hormone receptor positive breast cancer, particularly focusing on luminal A versus luminal B types.
  • Findings indicate that while SLNB did not significantly affect locoregional recurrence rates, it improved disease-free survival (DFS) and overall survival (OS) in luminal A patients, but had no notable benefits for luminal B patients.
  • Ultimately, the research suggests that SLNB may not be necessary for older patients with luminal B disease, as tumor biology, age, and comorbidities appear to drive patient outcomes more than the biopsy itself.

Article Synopsis
  • A 2016 guideline recommended that sentinel lymph node biopsy (SLNB) could be safely omitted in women aged 70 and older with specific breast cancer types, but no studies had evaluated adherence to this guideline in a cancer center.
  • A study examined data from 382 patients with hormone-receptor-positive, HER2-negative invasive breast cancer from 2005 to 2020, focusing on trends in SLNB use before and after the guideline was released.
  • Results showed no significant difference in SLNB application before and after the guideline, but increased adherence was noted among older patients and those not receiving certain types of radiation therapy, indicating that guideline adherence can improve over time but is also influenced by other factors.

Tomato yellow leaf curl virus (TYLCV) is a global spreading begomovirus that is exerting a major restraint on global tomato production. In this transgenic approach, an RNA interference (RNAi)-based construct consisting of sequences of an artificial microRNA (amiRNA), a group of small RNA molecules necessary for plant cell development, signal transduction, and stimulus to biotic and abiotic disease was engineered targeting the AC1/Rep gene of the Oman strain of TYLCV-OM. The Rep-amiRNA constructs presented an effective approach in regulating the expression of the Rep gene against TYLCV as a silencing target to create transgenic L.

China's housing distribution system has undergone a major transformation, and the country's housing markets have experienced a rapid price increase. However, the extent to which urban housing prices influence female labor participation (FLP) in labor decision-making and how the FLP rate affects economic development has not been sufficiently investigated. Accordingly, we first build a theoretical neoclassical economic development model that includes housing consumption factors to estimate the effect of housing price dynamics on FLP.

Jejunal diverticulitis is an uncommon pathology wherein a delay in diagnosis can lead to significant morbidity and mortality. We report a case of such diverticula requiring operative management, after patient failed non-operative management, likely due to advanced jejunal inflammation from a delay in diagnosis and subsequent management.

The importance of enterprises significantly improving their innovation performance by working closely with customers throughout the innovation process has been emphasized in recent literature. However, the role of organizational innovation environment in customer creativity and the impact of customer knowledge matching on the innovation environment are not sufficiently explored. Based on the Social cognitive theory and Flow theory, his investigate the factors that influence enterprise innovation performance in the context of customer participation in innovation, as well as how businesses can foster an online innovation environment that fosters customer creativity.

Introduction In Pakistan, the fourth wave of coronavirus disease 2019 (Covid-19) started around July 2021, which was dominated by the Delta variant of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus. The vaccination drive to immunize the people of Pakistan against Covid-19 was also going on during this period. There were multiple types of vaccines being administered to the people of Pakistan, as the vaccines had been procured from multiple sources.

Late, repetitive or chronic remote ischaemic conditioning (CRIC) is a potential cardioprotective strategy against adverse remodelling following ST-segment elevation myocardial infarction (STEMI). In the randomised Daily Remote Ischaemic Conditioning Following Acute Myocardial Infarction (DREAM) trial, CRIC following primary percutaneous coronary intervention (P-PCI) did not improve global left ventricular (LV) systolic function. A post-hoc analysis was performed to determine whether CRIC improved regional strain.

Article Synopsis
  • Mitral annular disjunction (MAD) is a structural heart abnormality characterized by a separation between the mitral valve and heart muscle, and its recognition in medical literature is growing.
  • A review of 12 studies involving nearly 4,000 patients found that MAD occurs in about 30.1% of individuals with mitral valve prolapse and has an overall prevalence of 8.7% in the general population, although the definition of MAD varies across studies.
  • Current evidence does not strongly link MAD to negative clinical outcomes, emphasizing the need for standardized definitions and management approaches.

A 31-year-old man presented to our emergency department with a 3-day history of progressive breathlessness, fatigue and exertional angina. His history included a mechanical aortic valve replacement (mAVR) for rheumatic heart disease at age 19 years. He could no longer afford medication prescription costs and consequently had not taken oral anticoagulation for 2 months.

Background: The pathophysiological and clinical significance of microvascular dysfunction (MVD) in patients with heart failure with preserved ejection fraction (HFpEF) remains uncertain.

Objectives: The aim of this study was to use cardiovascular magnetic resonance to: 1) quantify coronary microvascular function; 2) examine the relationship between perfusion and fibrosis; and 3) evaluate the impact of MVD and fibrosis on long-term clinical outcomes.

Methods: In a prospective, observational study, patients with HFpEF and control subjects underwent multiparametric cardiovascular magnetic resonance (comprising assessment of left ventricular volumetry, perfusion, and fibrosis [focal by late gadolinium enhancement and diffuse by extracellular volume]).
