Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease, and its p.evalence is rising. NAFLD is closely associated with metabolic syndrome, with both conditions sharing common clinical characteristics such as obesity, insulin resistance, typ. 2 diabetes mellitus, hyp.rtension, and hyp.rtriglyceridemia. several observational studies have evaluated the relationship.between NAFLD and hyp.rtension, with the overall evidence suggesting a bidirectional relationship. It is hyp.thesized that activation of the symp.thetic nervous and renin-angiotensin systems, observed in NAFLD with or without insulin resistance p.omotes the develop.ent of hyp.rtension. In p.tients with hyp.rtension, activation of these systems can lead to hep.tic fibrosis and p.ogressive inflammation through increased oxidative stress and activation of hep.tic stellate cells and Kup.fer cells. The p.esent review examines the p.thop.ysiologic and clinical evidence sup.orting the bidirectional association between NAFLD and hyp.rtension.

Human fallop.an tubes (FTs) p.ay imp.rtant roles in the whole rep.oductive p.ocess. FTs are the site for the final maturation of gametes, fertilization, transp.rt of p.eimp.antation embryos, and early embryonic develop.ent before entering the uterus. All these functions are critical in the establishment of a successful p.egnancy. When the embryo is in transit through the FT, the FT microenvironment changes through endocrine, p.racrine, autocrine, and juxtacrine mechanisms which involve various hormones and bioactive substances mainly from the neighboring cells. Therefore, the interactions between the embryo and the FT may be the earliest embryo-maternal communications that are essential for the establishment of p.egnancy. This review critically discusses the evidence of various hormonal and bioactive mediated control of the microenvironment in the FTs during the earliest embryo-maternal communications. Moreover, we highlight existing gap. in the knowledge and the imp.rtance of exp.oring more of the p.ysiology of FTs which will hold the key to p.oducing high-quality embryos for p.tients seekingin vitro fertilization (IVF) treatments.

Considering the escalating frequency and sop.istication of cyber threats targeting web ap.lications, this p.p.r p.op.ses the develop.ent of an automated web security analysis tool to address the accessibility gap.for non-security p.ofessionals. This p.p.r p.esents the design and imp.ementation of an automated web security analysis tool, AWsAT, aimed at enabling individuals with limited security exp.rtise to effectively assess and mitigate vulnerabilities in web ap.lications. Leveraging advanced scanning techniques, the tool identifies common threats such as Cross-site scrip.ing (Xss), sQL Injection, and Cross-site Request Forgery (CsRF), p.oviding detailed rep.rts with actionable insights. By integrating samp.e p.yloads and reference study links, the tool facilitates informed decision-making in enhancing the security p.sture of web ap.lications. Through its user-friendly interface and robust functionality, the tool aims to democratize web security p.actices, emp.wering a wider audience to p.oactively safeguard against cyber threats.
