Article Synopsis
  • This study evaluates the impact of sensor-based rehabilitation (SR) on chronic knee pain (CKP) by reviewing randomized controlled trials (RCTs) and cohort studies from various research databases.
  • Out of 937 screened studies, 10 studies with 4,347 patients were included; results showed some improvements in patient scores, especially when using avatar-based biofeedback with sensors.
  • However, overall evidence is insufficient to recommend routine use of SR for CKP, suggesting it might be more effective when combined with other treatment methods rather than just for tracking activity.

Article Synopsis
  • * It evaluates the strength, effectiveness, structure, and clinical potential of about 350 identified phenolic compounds, with 44 showing very strong antibacterial activity, primarily against Gram-positive bacteria.
  • * Key compounds like 2-Methoxy-7-methyljuglone and [6]-gingerol are noted as promising candidates for antibiotic development, indicating the significance of these plants in addressing bacterial infections.

Article Synopsis
  • - The study investigates the roles of circulating mRNAs (VEGF, PTEN, and SOCS1) in the progression of nasopharyngeal carcinoma (NPC) to better understand its molecular mechanisms and identify potential biomarkers for the disease.
  • - Researchers analyzed blood samples from 160 NPC patients and 80 controls, finding higher levels of VEGF and SOCS1 mRNAs in advanced stages of NPC, while PTEN mRNA was significantly decreased.
  • - The results suggest that changes in these mRNAs are linked to NPC progression and could be useful as biomarkers, though further research is needed to confirm their effectiveness in predicting outcomes for NPC patients.

The great majority of patients admitted to the intensive care unit (ICU) for critical gastrointestinal bleeding (GIB) will have a predictable etiology. Once the site is localized to the upper versus the lower gastrointestinal tract, the number of typically encountered etiological possibilities is quite limited. On rare occasions, the cause of GIB requiring ICU care is not one of the standard considerations, potentially leading to diagnostic and therapeutic delays.

Industrialization and agricultural demand have both improved human life and led to environmental contamination. Especially the discharge of a lot of poisonous and harmful gases, including ammonia, ammonia pollution has become a pressing problem. High concentrations of ammonia can pose significant threats to both the environment and human health.

Fluorine NMR is a highly sensitive technique for delineating the conformational states of biomolecules and has shown great utility in drug screening and in understanding protein function. Current fluorinated protein tags leverage the intrinsic chemical shift sensitivity of the F nucleus to detect subtle changes in protein conformation and topology. This chemical shift sensitivity can be amplified by embedding the fluorine or trifluoromethyl reporter within a pyridone.

This study aimed to investigate the prevalence of social anxiety disorder (SAD) among Malaysian secondary school students during the COVID-19 pandemic and to explore its correlations with demographic variables, impulsivity behavior, and internet gaming disorder (IGD). A total of 1574 participants from 12 government secondary schools across five Malaysian states, comprising 569 males and 1005 females, completed an online questionnaire containing validated Malay versions of the Social Interaction Anxiety Scale, Barratt Impulsiveness Scale, and Internet Gaming Disorder Scale - Short Form. The findings revealed a notable SAD prevalence rate of 40.

Organohalides are recalcitrant, toxic environmental pollutants. Reductive dehalogenase enzymes (RDases) found in organohalide respiring bacteria (OHRB) utilise organohalides as electron acceptors for cellular energy and growth, producing lesser-halogenated compounds. Consequently, microbial reductive dehalogenation via organohalide respiration represents a promising solution for clean-up of organohalide pollutants.

Objective: To evaluate the effectiveness of intralesional bleomycin in comparison to cryotherapy in the treatment of cutaneous warts.

Methods: The randomized controlled trial was conducted at the Department of Dermatology, Jinnah Postgraduate Medical Centre, Karachi, from January to July 2021, and comprised patients of either gender aged 18-60 years who had cutaneous warts for 1-48 weeks. The subjects were divided into group A treated with 0.

SAH (subarachnoid hemorrhage) caused by aneurysm rupture has the greatest mortality rate, with nearly 50% of patients unable to survive beyond 1 month after the attack. Anterior choroidal artery (AChA) aneurysms are one of the most difficult to treat among the numerous types of aneurysms. Until now, some neurosurgeons employed shearing while others employed coiling.

Attention deficit is one of the most prominent and disabling symptoms in Fragile X syndrome (FXS). Hypersensitivity to sensory stimuli contributes to attention difficulties by overwhelming and/or distracting affected individuals, which disrupts activities of daily living at home and learning at school. We find that auditory or visual distractors selectively impair visual discrimination performance in humans and mice with FXS but not in typically developing controls.

Management of COVID-19 in Africa is challenging due to limited resources, including the high cost of vaccines, diagnostics, medical devices and routine pharmaceuticals. These challenges, in addition to wide acceptability, have resulted in increased use of herbal medicines based on African traditional medicines (ATMs) by patients in Africa. This is in spite of the often-significant gaps in evidence regarding these traditional medicines as to their efficacy and safety for COVID-19.

Since the COVID-19 pandemic, telemedicine or non-face-to-face medicine has increased significantly. In practice, various types of medical images are essential to achieve effective telemedicine. Medical image encryption algorithms play an irreplaceable role in the fast and secure transmission and storage of these medical images.

The biosynthesis of nanoparticles using the green route is an effective strategy in nanotechnology that provides a cost-effective and environmentally friendly alternative to physical and chemical methods. This study aims to prepare an aqueous extract of (-based silver nanoparticles (AgNPs) through the green route and test their antibacterial activity. The biosynthesized silver nanoparticles were characterised by colour change, UV spectrometric analysis, FTIR, and particle shape and size morphology by SEM and TEM images.

Discriminating between temporal features in sensory stimuli is critical to complex behavior and decision-making. However, how sensory cortical circuit mechanisms contribute to discrimination between subsecond temporal components in sensory events is unclear. To elucidate the mechanistic underpinnings of timing in primary visual cortex (V1), we recorded from V1 using two-photon calcium imaging in awake-behaving mice performing a go/no-go discrimination timing task, which was composed of patterns of subsecond audiovisual stimuli.

Objective: To assess the prevalence of mask acne in general population and healthcare workers, and the association of acne breakout due to mask-wearing with different factors.

Methods: The prospective, cross-sectional study was conducted from January to April 2022 at the Dermatology Department of Aga Khan University Hospital, Karachi, and comprised patients of both genders of all ages who received acne treatment during the period. Data was collected using a self-designed questionnaire having Cronbach's alpha value 0.

The WHO declared coronavirus disease 2019 (COVID-19) a pandemic in March 2020, which was caused by novel coronavirus severe acute respiratory coronavirus 2 (SARS-CoV-2). SARS-CoV-2 made its first entry into the world in November 2019, and the first case was detected in Wuhan, China. Mutations in the SARS-CoV-2 genome distressed life in almost every discipline by the extended production of novel viral variants.

Heterotrimeric G proteins serve as membrane-associated signaling hubs, in concert with their cognate G-protein-coupled receptors. Fluorine nuclear magnetic resonance spectroscopy was employed to monitor the conformational equilibria of the human stimulatory G-protein α subunit (Gα) alone, in the intact Gαβγ heterotrimer or in complex with membrane-embedded human adenosine A receptor (AR). The results reveal a concerted equilibrium that is strongly affected by nucleotide and interactions with the βγ subunit, the lipid bilayer and AR.
