Synthesis, and bio-evaluation studies of new isothiocyanate derivatives with respect to COX inhibition and HS release profiles.

The development of HS-donating derivatives of non-steroidal anti-inflammatory drugs (NSAIDs) is considered important to reduce or overcome their gastrointestinal side effects. Sulforaphane, one of the most extensively studied isothiocyanates (ITCs), effectively releases HS at a slow rate. Thus, we rationally designed, synthesized, and characterized new ITC derivatives (I1-3 and I1a-e) inspired by the natural compound sulforaphane.

Overlapping clinical features of persistent fetal vasculature and combined hamartoma of the retina and retinal pigment epithelium.

Purpose: To investigate cases exhibiting overlapping features of persistent fetal vasculature (PFV) and combined hamartoma of the retina and retinal pigment epithelium (CHRRPE) and to explore potential associations between these developmental ocular anomalies.

Methods: This retrospective, descriptive case series included 9 eyes of 8 patients aged 0-7 years with shared clinical features of PFV and CHRRPE. Diagnoses were established through clinical examination and intraoperative findings.

Selagibenzophenone B and Its Derivatives: , a Dual Topoisomerase I/II Inhibitor Identified through In Vitro and In Silico Analyses.

The development of multitargeted drugs represents an innovative approach to cancer treatment, aiming to enhance drug effectiveness while minimizing side effects. Herein, we sought to elucidate the inhibitory effect of selagibenzophenone B derivatives on the survival of cancer cells and dual topoisomerase I/II enzyme activity. Results demonstrated that among the compounds, selectively inhibited the proliferation and migration of prostate cancer cells while exhibiting minimal effects on healthy cells.

Effect of Portal Vein Types on Estimated Remnant Volume in Living Donor: Preoperative CT Assessment.

Purpose: The aim of this study is to examine the effect of portal vein types on the ratio of the right-left lobe liver volumes, as well as the insufficient estimated remnant liver volume (ERLV) during the preoperative assessment of donor candidates for right-lobe liver transplantation.

Materials And Methods: The preoperative abdominal CT examinations of the donor candidates in a single institution between December 2018 and May 2022 were retrospectively evaluated. Portal vein types are divided into 3; classical anatomy was considered type 1, PV trifuction was considered type 2, and if the first branch arising from the main portal vein is the right posterior branch, it was accepted as type 3.

The impact of intraoperative neural monitoring during papillary thyroid cancer surgery on completeness of thyroidectomy and thyroglobulin response: a propensity-score matched study.

Background: Intraoperative neural monitoring (IONM) has been utilized for a variety of thyroid pathologies, including papillary thyroid carcinoma (PTC). Remnant thyroid tissue following total thyroidectomy (TT) in patients with PTC is associated with increased recurrence. The aim of this study is to investigate whether the use of IONM in PTC surgery has an impact on the completeness of thyroidectomy.

Synthesis of new imine-/amine-bearing imidazo[1,2-a]pyrimidine derivatives and screening of their cytotoxic activity.

Imidazo[1,2-]pyrimidine derivatives bearing imine groups (-) were successfully synthesized in moderate to good yields using microwave-assisted heating. Corresponding amine derivatives (-) were also obtained by the reduction reaction of the imine derivatives (-). All synthesized products were characterized by FT-IR, H NMR, C NMR, and LC-MS spectroscopic techniques.

Pancreatic steatosis is an independent risk factor for post-transplant diabetes mellitus in kidney transplant patients.

Background And Aim: Post-transplant diabetes mellitus (PTDM) is associated with an increased risk of post-transplant cardiovascular diseases, and several risk factors of PTDM have been shown in the literature. Yet, the relationship between hepatic and pancreatic steatosis with post-transplant diabetes mellitus remains vague. We aimed to evaluate pancreatic steatosis, a novel component of metabolic syndrome, and hepatic steatosis association with post-transplant diabetes mellitus in a single-center retrospective cohort study conducted on kidney transplant recipients.

The Biomimetic Synthesis of Polyarylated Fluorenes, Relevant to Selaginellaceae Polyphenols, Leading to the Spontaneous Formation of Stable Radicals.

This work reports a biomimetic synthesis of polyarylated fluorene derivatives. The molecules are formed via intramolecular electrophilic aromatic substitution, resembling a cyclization leading towards the natural selaginpulvilins from selaginellins. The scope of the reaction was investigated, and the products were obtained in 60-95 % yields.

Severe anterior persistent fetal vasculature: the role of anterior retinal elongation on prognosis.

Purpose: This study aims to investigate surgical outcomes of eyes with severe anterior persistent fetal vasculature (PFV) and the role of associated anatomical anomalies on prognosis.

Methods: This is a retrospective, comparative case series of 32 eyes of 31 patients who underwent vitreoretinal surgery for severe anterior PFV, defined as fibrovascular tissue totally covering the back of cataractous lens. Based on the degree of anterior retinal elongations, cases were classified as follows: group 1, eyes with well-developed pars plana and minor/no abnormalities (n = 11, 34%); group 2, eyes with partially developed pars plana and broad-based elongations (n = 9, 28%); and group 3, eyes with no visible pars plana and fibrovascular membrane having 360° continuity with peripheral retina (n = 12, 38%).

Surveillance of hemodialysis related infections: a prospective multicenter study.

As in many countries, there is neither a surveillance system nor a study to reveal the hemodialysis (HD) related infection rates in Turkey. We aimed to investigate the infection rate among HD outpatients and implement CDC's surveillance system. A multicenter prospective surveillance study is performed to investigate the infection rate among HD patients.

Looking at NSAIDs from a historical perspective and their current status in drug repurposing for cancer treatment and prevention.

Non-steroidal anti-inflammatory drugs (NSAIDs) are one of the most frequently prescribed drug classes with wide therapeutic applications over the centuries. Starting from the use of salicylate-containing willow leaves to the recent rise and fall of highly selective cyclooxygenase-2 (COX-2) inhibitors and the latest dual-acting anti-inflammatory molecules, they have displayed a rapid and ongoing evolution. Despite the enormous advances in the last twenty years, investigators are still in search of the design and development of more potent and safer therapy against inflammatory conditions.

Subjects/methods: Retrospective, single surgeon, consecutive case series of 52 eyes of 44 patients with posterior PFVS who underwent VRS. Cases were divided into "tent-shaped TRD" and "funnel-shaped TRD" groups based on the preoperative TRD configuration.

Pseudo-hyaloidal Stalk in Anterior Persistent Fetal Vasculature: A Report of Two Cases.

Persistent fetal vasculature (PFV) syndrome is characterized by abnormal regression of the fetal hyaloid system and may occur in various forms. In this report, two atypical cases associated with posterior capsular defect and ectopic lens material located along Cloquet's canal are discussed. Ultrasonography of these patients presenting with bilateral total cataracts revealed a hyaloidal stalk extending from the optic nerve head to the retrolental area.
