Targeting gut microbiota dysbiosis in inflammatory bowel disease: a systematic review of current evidence.

Introduction: The dysbiosis of the gut microbiota has been identified as a central factor in the pathogenesis of inflammatory bowel disease (IBD), a chronic condition characterized by frequent recurrence and various adverse effects of traditional therapies. While treatments targeting the gut microbiota show promise, their efficacy in IBD management still requires extensive evaluation. Our systematic review analyzes recent studies to elucidate the advancements and challenges in treating IBD using microbial-based therapies.

Microbial signatures and therapeutic strategies in neurodegenerative diseases.

Neurodegenerative diseases (NDs), including Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), and multiple sclerosis (MS), arise from complex interactions between genetic factors, environmental exposures, and aging. Additionally, gut dysbiosis has been linked to systemic inflammation and neurodegeneration. Advances in microbiome and metabolome profiling techniques have provided deeper insights into how alterations in gut microbiota and dietary patterns affect metabolic pathways and contribute to the progression of NDs.

Background: Metabolic syndrome (MetS) is a chronic disorder featuring overweight/obesity, high blood pressure, and dysfunction of lipid and carbohydrate metabolism. Microbiome-modulating probiotics, prebiotics, synbiotics and fecal microbiota transplant (FMT) are promising adjunct therapies for improving parameters of glucose homeostasis and insulinemia.

Methods: We conducted a comprehensive systematic review, meta-analyses, and meta-regressions to investigate the effect of the abovementioned microbiome therapies on various biomarkers after screening clinical trials published through April 2023.

Experimental and computational investigation of the effect of Hsc70 structural variants on inhibiting amylin aggregation.

The misfolding and aggregation of human islet amyloid polypeptide (hIAPP), also known as amylin, have been implicated in the pathogenesis of type 2 diabetes (T2D). Heat shock proteins, specifically, heat shock cognate 70 (Hsc70), are molecular chaperones that protect against hIAPP misfolding and inhibits its aggregation. Nevertheless, there is an incomplete understanding of the mechanistic interactions between Hsc70 domains and hIAPP, thus limiting their potential therapeutic role in diabetes.

A cord of four strands: Perspective of pre-medical and medical students on combined teaching modalities in undergraduate biochemistry.

Despite being a traditional coursework for pre-medical and medical students around the globe, biochemistry education suffers from a lack of positive appreciation due to the nature of the subject combined with deficiency of teaching modalities. A first semester biochemistry course was designed to include four different teaching modalities: lectures, recitations, case studies, and student presentations. A multi-item, anonymous, and voluntary questionnaire was distributed to students who had just completed the course and to those who had taken it the previous year.

Microbiome-modulating nutraceuticals ameliorate dyslipidemia in type 2 diabetes: A systematic review, meta-analysis, and meta-regression of clinical trials.

Aims: Type 2 Diabetes is intrinsically linked to cardiovascular disease (CVD) via diabetic dyslipidemia, both of which remain global health concerns with annually increasing prevalence. Given the established links between gut microbiome dysbiosis and metabolic diseases, its modulation is an attractive target to ameliorate metabolic imbalances in such patients. There is a need to quantitively summarise, analyse, and describe future directions in this field.

Deep Brain Stimulation beyond the Clinic: Navigating the Future of Parkinson's and Alzheimer's Disease Therapy.

Deep brain stimulation (DBS) is a surgical procedure that uses electrical neuromodulation to target specific regions of the brain, showing potential in the treatment of neurodegenerative disorders such as Parkinson's disease (PD) and Alzheimer's disease (AD). Despite similarities in disease pathology, DBS is currently only approved for use in PD patients, with limited literature on its effectiveness in AD. While DBS has shown promise in ameliorating brain circuits in PD, further research is needed to determine the optimal parameters for DBS and address any potential side effects.

Accounting for nearly 8% of global deaths (4.7 million) in 2017, obesity leads to diminishing quality of life and a higher premature mortality rate among affected individuals.

Knowledge, Awareness, and Attitude of Healthcare Stakeholders on Alzheimer's Disease and Dementia in Qatar.

Dementia is characterized by progressive cognitive decline, memory impairment, and disability. Alzheimer's disease (AD) accounts for 60-70% of cases, followed by vascular and mixed dementia. Qatar and the Middle East are at increased risk owing to aging populations and high prevalence of vascular risk factors.

Evaluating the inhibitory potential of natural compound luteolin on human lysozyme fibrillation.

Numerous pathophysiological conditions known as amyloidosis, have been connected to protein misfolding leading to aggregation of proteins. Inhibition of cytotoxic aggregates or disaggregation of the preformed fibrils is thus one of the important strategies in the prevention of such diseases. Growing interest and exploration of identification of small molecules mainly natural compounds can prevent or delay amyloid fibril formation.

A multi-targeted approach to identify potential flavonoids against three targets in the SARS-CoV-2 life cycle.

The advent and persistence of the Severe Acute Respiratory Syndrome Coronavirus - 2 (SARS-CoV-2)-induced Coronavirus Disease (COVID-19) pandemic since December 2019 has created the largest public health emergency in over a century. Despite the administration of multiple vaccines across the globe, there continues to be a lack of approved efficacious non-prophylactic interventions for the disease. Flavonoids are a class of phytochemicals with historically established antiviral, anti-inflammatory and antioxidative properties that are effective against cancers, type 2 diabetes mellitus, and even other human coronaviruses.

A Capstone Laboratory theme investigating properties of non-steroidal anti-inflammatory drugs and their solubilization by cationic surfactant micelles.

Research experience is becoming an increasingly crucial element of today's undergraduate science curriculum. In recent years, the establishment of the Course-Based Undergraduate Research Experience Network (CUREnet) has provided a framework for the development of courses aiming to cultivate students' proficiency in undergraduate research techniques while fostering scientific curiosity in a laboratory setting. Capstone Laboratory is one such course that was designed to provide second-year pre-medical students at Weill Cornell Medicine-Qatar with exposure to laboratory techniques to develop their repertoire of research skills.

Converting a formerly in-person biochemistry course based undergraduate research experience to online teaching during the COVID-19 pandemic.

The COVID-19 pandemic had a significant impact on the delivery of undergraduate courses around the world, and this was no different for the Biochemistry Capstone course offered to Weill Cornell Medicine-Qatar's second year pre-medical students during the 2021 spring semester. The course, which was previously delivered in-person and offered an opportunity for students to familiarize themselves with research and laboratory techniques, had to be modified to be delivered online. The online delivery of the course mainly consisted of "Zoom" sessions, "Canvas" materials, and data analysis using Microsoft Excel raw data sheets.
