  • The study aimed to compare patients with seronegative and seropositive primary Sjögren's syndrome (pSS) by analyzing their medical records from 2010 to 2023.
  • Key findings revealed that seropositive patients exhibited more extraarticular manifestations, while dry mouth was notably more common in seronegative patients.
  • Additionally, while the two groups showed similar rates of certain complications, seropositive patients accounted for all the deaths observed in the study.

Cancer, defined by the continuous, uncontrollable proliferation of cells in the human body, is a disease with a rapidly increasing incidence and mortality rate. Scientists are looking for novel ways to cure and prevent this sneaky disease because of the toxicity of contemporary chemotherapy and the cancer cells' resilience to anticancer drugs. Determining the effect of herbal medicines, which do not have as harmful side effects as synthetic drugs, on cancer cell lines is an essential preliminary study in the production of effective drugs against cancer.

This study aims to investigate the effects of lycopene on apoptotic, autophagic, and necrotic pathways, oxidative status, and DNA damage in diabetic nephropathy at the molecular level. The sample of the study includes seven groups: lycopene (L), high glucose (G), high glucose + lycopene (GL), and control (C) groups tested at 12 and 24 h. The expression levels of genes in oxidative, apoptotic, autophagic, and necrotic cell death pathways are determined by reverse transcription-quantitative polymerase chain reaction analysis.

Background: Trichobezoar is a rare clinical condition in children, which is caused by the accumulation of swallowed hair mass in the digestive tract. This condition is most common in young women with psychiatric histories who suffer from trichotillomania (TTM), where they have an irresistible urge to pull out their hair. Diagnosis and treatment of this pathology, which is already extremely rare, and its variable clinical presentations are challenging.

Article Synopsis
  • - Trichomoniasis is a parasitic sexually transmitted infection caused by Trichomonas vaginalis, and its diagnosis can be done using various methods, with direct microscopy being the quickest but least sensitive, while culture methods are more accurate but slower and resource-dependent.
  • - The study aimed to compare the effectiveness of conventional microscopic and culture methods against the polymerase chain reaction (PCR) method for diagnosing T. vaginalis, as well as investigate gene polymorphisms thought to relate to metronidazole resistance in samples from 200 patients.
  • - Researchers collected vaginal swab samples from patients and tested them with multiple methods, finding that only 4% of the samples were positive for T. vaginalis with both culture/staining and

Background: Out of all measure systemic exposure to fluorides can cause defect of skeletal and dental fluorosis. Endoplasmic reticulum (ER) stress is caused by fluorine-induced oxidative stress and importance of vitamin D in its prevention is not known enough in bone cells. This study was carried out to investigate fluorine-induced oxidative stress, ER stress, and death pathways and the effect of vitamin D on them.

Objective: Laparoscopic surgery is the favored method for the surgical treatment of gynecologic diseases and malignancies. We have defined an anatomic landmark-based, easy-to-perform, and an alternative way of open laparoscopic entry technique named the ligamentum teres lift-up technique (TLU) that can be used in obese or normal-weight women to tackle the risks of the closed laparoscopic entry technique, namely, Veress needle entry (VNE).

Study Design: In this retrospective comparative study, the participants were equally distributed to either the TLU group (n = 36) or the VNE group (n = 36) in a 1:1 ratio.

Article Synopsis
  • - A new study synthesized pyrimidine-coupled -β-glucosides and their tetra-acetyl derivatives, focusing on their antimicrobial and anticancer properties compared to existing chemotherapeutics.
  • - The findings indicated strong antiproliferative effects (with activities ranging from 2.29 to 66.84 μg/mL) and significant antibacterial activity against pathogenic bacteria, along with notable cytotoxicity percentages.
  • - Molecular docking studies supported these results, showing that the new compounds bind effectively to CT-DNA, suggesting their potential as promising chemotherapeutic agents deserving further study.

Papillomaviruses, known as epitheliotropic, cause proliferation in the skin, mucosa, and different visceral organs. In this study, it was aimed to diagnose bovine papillomavirus (BPV) by using different methods in the lesion taken from twenty cattle with papillomas in different areas of the body and to reveal its molecular characterization. In our study, molecular, immunohistochemistry, and transmission electron microscopy (TEM) methods were used for virus identification.

This study aimed to predict some soil water contents and soil erodibility indices with a multilayer perceptron (MLP) artificial neural network (ANN) using remote sensing data (Landsat 8 OLI TIRS) and topographic variables from a digital elevation model (DEM) in a semi-arid ecosystem. In models, the input variables were derived from remote sensing imaging and DEM. The output variables were field capacity, wilting point, aggregate stability index, structural stability index, dispersion ratio, and clay flocculation index.

Papillomaviruses are epitheliotropic in nature and cause proliferation in the skin, mucosa, and various internal organs of various animal species. The lesions they cause, specifically in cattle teats, lead to significant economic losses in the milk industry. In this study, we identified the bovine papillomaviruses (BPVs) responsible for teat papillomas in cattle.

Article Synopsis
  • The study aimed to explore the effects of L-theanine on liver injury caused by ischemia-reperfusion in rats, which is a condition where blood supply to the liver is temporarily cut off and then restored.
  • Thirty-two male Sprague Dawley rats were divided into four groups, some receiving L-theanine while others did not, to investigate changes in liver cell injury and function markers following induced ischemia-reperfusion.
  • The results indicated that L-theanine reduced liver damage and improved various biochemical markers associated with hepatic injury, suggesting its potential protective role, though further research is necessary to confirm its effects.
