MD-1 is a time-tested polyherbal diabetes supplement in Tamil Nadu, India. It is composed of dried powdered herbs: Phyllanthus amarus Schum. & Thonn, Tinospora cordifolia (Willd.) Miers ex Hook. F. & Thoms, Emblica officinalis Gaertn., Eugenia jambolana Lam., Gymnema sylvestre R. Br. Ex, and Cassia auriculata Linn. This study aimed to investigate the in vivo effects of MD-1 in high-fat diet (HFD)-induced diabetes mellitus in C57BL/6J mice.

After 10 weeks of HFD induction, diabetic mice (n = 60) were randomized to 21-day treatments with MD-1, metformin, or left untreated on a standard pellet diet. Fasting blood glucose, triacylglycerol (TAG), total cholesterol, and liver tissue markers including superoxide dismutase, glutathione peroxidase, glutathione, thiobarbituric acid reactive substance, glucokinase, fructose-1,6-bisphosphatase, and glucose-6-phosphatase expressions were measured. Adipose tissue tumor necrosis factor (TNF)-α infiltration and messenger RNA expression of peroxisome proliferator-activated receptor γ (PPAR-γ) and glucose transporter type 4 (Glut4) were also analyzed.

MD-1 treatment significantly reduced elevated fasting blood glucose, TAG, and total cholesterol in HFD-fed mice and countered HFD-induced weight gain despite unchanged caloric intake. Improved adipose tissue function was evidenced by reduced TNF-α infiltration and increased messenger RNA expression of PPAR-γ and Glut4. MD-1 attenuated HFD-induced fatty liver disease by reducing oxidative stress and TAG accumulation, suggesting a possible two-hit mechanism.

MD-1 administration primarily targets adipose tissue TNF-α signaling in HFD mice, restoring function via PPAR-γ/Glut4 expression. These findings support its glycemic intervention potential and justify its supplementation in diabetes.

Coronary heart disease is an ischemic condition characterized by vascular stenosis or obstruction caused by coronary atherosclerosis, resulting in myocardial ischemia, hypoxia, or necrosis. It is one of the leading causes of death in both urban and rural populations in China. Safflower yellow pigments, the main active components of the traditional Chinese herbal medicine safflower, are primarily composed of quinochalcone compounds, including hydroxysafflor yellow A and anhydrosafflor yellow B—of which hydroxysafflor yellow A is the principal component. Studies have demonstrated that these pigments can improve myocardial ischemia, reduce ischemia-reperfusion injury, alleviate atherosclerotic damage, and address risk factors associated with coronary heart disease. This review aimed to systematically and comprehensively summarize the mechanisms of action of safflower yellow pigments and their active components in the context of coronary heart disease and its related risk factors.

Histologic remission is recommended as an adjunctive treatment target in ulcerative colitis, and scoring systems have been proposed to enhance reproducibility. The Nancy Histologic Index (NHI) is increasingly used in clinical trials; however, its performance in real-world settings is not fully established. This study aimed to assess the interrater reliability (IRR) of the NHI among gastrointestinal pathologists in the United States.

Thirty-seven whole-slide images of colorectal biopsies from 34 treated ulcerative colitis patients enrolled in a multicenter adult cohort were independently reviewed by 12 gastrointestinal pathologists. Each biopsy was reviewed twice, five months apart, and graded using the NHI. Prior to the second review, pathologists completed an online tutorial on the NHI.

The NHI showed substantial IRR in both reviews [intraclass correlation coefficient (ICC) = 0.79; 95% confidence interval (CI), 0.70–0.87 at Review 1; ICC = 0.78; 95% CI, 0.69–0.86 at Review 2]. However, considerable variability was observed in individual grade assignments, with the lowest IRR for Grade 2 (ICC = 0.24; 95% CI, 0.15–0.37; P < 0.001, and ICC = 0.23; 95% CI, 0.14–0.36; P < 0.001 for Reviews 1 and 2, respectively), followed by Grade 4 (ICC = 0.41; 95% CI, 0.29–0.55; P < 0.001, and ICC = 0.47; 95% CI, 0.35–0.61; P < 0.001). Grade 1 showed the highest IRR (ICC = 0.79; 95% CI, 0.70–0.87; P < 0.001, and ICC = 0.78; 95% CI, 0.69–0.86; P < 0.001). When Grades 2, 3, and 4 (i.e., active disease) were grouped together, the IRR remained substantial across both reviews (ICC = 0.76; 95% CI, 0.66–0.85; P < 0.001).

While the substantial IRR for active disease (Grades ≥ 2) in this study underscores the clinical utility of the NHI, refinement of criteria for Grades 2, 3, and 4 will be crucial in reducing variability among observers and enabling more accurate monitoring of treatment endpoints.

Infection control is essential for the success of prosthodontic and oral implant procedures, as microbial contamination can lead to serious complications such as denture stomatitis and peri-implantitis. While synthetic disinfectants like chlorhexidine are commonly used, they may cause side effects including irritation, toxicity, and the development of microbial resistance over time. Natural products derived from plants, animals, and minerals are currently being explored as safer alternatives. Compounds such as epigallocatechin gallate from green tea; eugenol from clove oil; quercetin, thymol, cinnamaldehyde, and flavonoids from propolis; and terpinen-4-ol from tea tree oil have shown strong antimicrobial and anti-biofilm properties. These natural agents are not only effective against harmful oral bacteria but also promote healing, are more biocompatible, environmentally friendly, and are often preferred by patients. However, challenges remain regarding their routine clinical use. The strength and composition of natural agents can vary, and there is a lack of consistent product standards, clinical trials, and comprehensive safety data. Currently, these products are not approved by the U.S. Food and Drug Administration for dental use and are only available as over-the-counter remedies. Production costs and scalability must also be evaluated in comparison with synthetic alternatives. Emerging technologies, such as nanocarriers and targeted delivery systems, are being developed to enhance the effectiveness of natural agents in dental applications. Further clinical research and the establishment of clear regulatory guidelines are necessary to support their integration into clinical practice. Natural disinfectants hold significant potential to become valuable, safe, and sustainable tools for maintaining hygiene in prosthodontics and oral implantology.

Macromolecular-based gene delivery systems have emerged as viable alternatives to non-viral vectors for gene therapy due to their versatility, biocompatibility, and capacity to efficiently deliver therapeutic cargo. These systems, primarily based on synthetic and natural polymers, offer significant advantages in terms of safety, controlled gene release, and targeted delivery. This review explores the design and synthesis of macromolecular carriers, focusing on their chemical and physical architectures, which play a key role in improving gene delivery. Catanionic polymers and their derivatives (comb, brush, and star polymers) have been extensively researched for their capacity to condense and protect genetic material. Furthermore, natural polymers like chitosan and hyaluronic acid have been modified to enhance gene delivery capabilities. These macromolecular carriers are engineered to boost circulation time, increase cellular uptake, and facilitate the controlled release of genetic material at the target site. Strategies such as incorporating targeting ligands, stimuli-responsive elements, and reducing cytotoxicity are being pursued to improve the overall efficiency and specificity of these systems. This review highlights the current state of macromolecular gene delivery systems, their applications, and the ongoing research aimed at overcoming existing challenges, paving the way for more effective non-viral gene therapies.

Liver failure syndromes are characterised by a dysregulated immune response leading to immune paralysis. Adrenomedullin (ADM) is a potent vasodilator and immunoregulator. This study aimed to explore the role of ADM in liver failure, hypothesising that there is a detrimental imbalance between ADM and adrenomedullin binding protein (AMBP)1 that promotes a switch of monocytes/macrophages towards a pro-restorative phenotype and function.

Consecutive patients with acute liver failure (ALF), acute-on-chronic liver failure (ACLF), and decompensated cirrhosis, as well as healthy controls (HC) were included between April 2020 and June 2024. Peripheral blood mononuclear cells/monocytes were isolated and used for RNA sequencing and cell culture. ADM and AMBP1 were measured by enzyme-linked immunosorbent assay.

Fifty-four patients with ALF, 25 with ACLF, 9 with decompensated cirrhosis, and 16 with HC were included. ADM expression in isolated monocytes was increased in ALF (log fold change = 5.88, p = 0.000216413) and ACLF (log fold change = 4.62, p = 0.00057122) compared to HC. Plasma ADM concentration was higher in ALF (1,684 ± 1,156 pg/mL) vs. ACLF (836.1 ± 765.2 pg/mL) and HC (164.8 ± 62.73 pg/mL). AMBP1 was significantly reduced in ALF (59.27 ± 44 µg/mL) vs. ACLF (126.3 ± 72.23 µg/mL) and HC (252.8 ± 159.7 µg/mL) (p < 0.0001, ALF vs. HC). Treatment with LPS increased ADM concentration in peripheral blood mononuclear cell supernatant (ALF n = 6; 561.4 ± 1,038 pg/mL vs. 259.2 ± 213.7 pg/mL, ACLF n = 4; 3,202 ± 491.2 vs. 1,757 ± 1,689 pg/mL). The percentage of CD14+ cells expressing Mer tyrosine kinase was reduced after culture with LPS (2.077 ± 0.87%); however, co-culture with ADM 100 nM restored the phenotype (3.852 ± 1.063%).

ADM is increased in liver failure, whereas AMBP1 is reduced. ADM affects monocyte function, increasing Mer Tyrosine Kinase and promoting a pro-restorative, anti-inflammatory phenotype.

Soft tissue cytopathology plays a vital role in the diagnosis and management of soft tissue neoplasms, necessitating a standardized classification system to improve diagnostic accuracy and guide clinical decision-making. This article provides a concise review of the World Health Organization (WHO) Reporting System for Soft Tissue Cytopathology and presents a practical diagnostic approach to soft tissue cytopathology.

The WHO Reporting System is reviewed in conjunction with relevant literature. The reporting system employs a six-category framework: non-diagnostic, benign, atypical, soft tissue neoplasm of uncertain malignant potential, suspicious for malignancy, and malignant. Each category is associated with a corresponding risk of malignancy and recommended clinical management guidelines. This classification aligns with the WHO Classification of Soft Tissue and Bone Tumours (5th edition) and incorporates cytomorphologic features, ancillary studies, and clinical correlation to enhance diagnostic reproducibility and communication among pathologists and clinicians.

The system supports a probabilistic approach to risk stratification, enabling more consistent diagnostic and therapeutic strategies.

As molecular diagnostics and immunocytochemistry continue to advance, this framework provides a robust foundation for the interpretation of soft tissue fine-needle aspiration biopsies and optimized patient care.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a leading cause of hepatic fibrosis, yet its prevalence in asymptomatic populations remains unclear. This study aimed to assess the prevalence of steatosis and significant fibrosis in asymptomatic individuals without known liver disease in the Greater Vancouver Area.

Interested individuals voluntarily registered online via the Canadian Liver Foundation website or by telephone. Inclusion criteria included age ≥ 19 years, no known liver disease, and low alcohol intake (<30 g/day for men, <20 g/day for women). Demographic and clinical data were collected, and all participants underwent transient elastography after a 3-h fast. The study aimed to collect 4,500 analyzable scans while reflecting the region’s ethnic diversity.

A total of 4,193 participants were analyzed. The median age was 62 years, the median body mass index was 25.4, and 45% were male. Asian individuals comprised 42% of the cohort. Steatosis was present in 59.6% of participants, and 45.7% met diagnostic criteria for MASLD. Significant fibrosis (F2–F4) was found in 8.6%. Age, male sex, ethnicity, cardiac disease, diabetes, hypertension, and obesity were significantly associated with fibrosis. Logistic regression analysis confirmed age, weight, diabetes, dyslipidemia, hypertension, and obesity as independent predictors.

A substantial proportion of asymptomatic individuals in Greater Vancouver have undetected MASLD and significant fibrosis. Early identification of high-risk groups may support broader implementation of transient elastography screening. This study provides one of the first North American population-based estimates of MASLD and fibrosis stratified by ethnicity, offering new insights into liver disease distribution among Caucasian, Chinese, and South Asian populations.
