The indiscriminate use of herbal products is increasingly growing worldwide; nonetheless consumers are not warned about the potential health risks that these products may cause. Hintonia latiflora (Hl) is a tree native to the American continent belonging to the Rubiaceae family and its stem bark is empirically used mainly to treat diabetes and malaria; supplements containing Hl are sold in America and Europe without medical prescription, thus scientific information regarding its toxicity as a consequence of a regular consumption is needed...

The tumor necrosis factor (TNF)-α- induced protein 8 (TNFAIP8/TIPE) family is a death effector domain (DED)-containing protein family with four identified members: TNFAIP8 (TIPE), TNFAIP8L1 (TIPE1), TNFAIP8L2 (TIPE2), and TNFAIP8L3 (TIPE3). These proteins were found to play crucial roles in the regulation of immune homeostasis, inflammation, and cancer development. Intensive research in the past two decades revealed a strong correlation of TIPE proteins with development of various cancers including cancers of the bladder, blood, bone, breast, cervix, colon, esophagus, endometrium, stomach, liver, lung, ovary, pancreas, prostate, and thyroid gland...

Historically, piscine francisellosis in various warm, temperate and coldwater fish hosts has been attributed to Francisella noatunensis From 2015-2016, an undescribed Francisella sp. was recovered during mortality events in cultured spotted rose snapper ( Lutjanus guttatus ) off the Pacific coast of Central America. Despite high mortality and emaciation, limited gross findings were observed in affected fish. Histological examination revealed multifocal granulomatous lesions, with the presence of numerous small, pleomorphic coccobacilli, predominantly in the peritoneum, spleen, kidneys, liver, pancreas, heart, and intestine...

A 79-year-old woman presented with a large fresh rectal bleed. Computed tomography revealed that she had a large type IV hiatus hernia, which contained the stomach and pancreas. Compression of the inferior mesenteric vein and splenic vein had led to thrombosis within these vessels and retrograde flow within the inferior mesenteric vein. This had led to the formation of portosystemic rectal varices. Ectopic varices occasionally form in the rectum, often in the context of liver cirrhosis. At the time of writing, ours is the first reported case of portosystemic rectal varices formulated in response to obstruction of vessels within a hiatus hernia...

Vitamin D3 deficiency was found to be tightly linked to many health problems including metabolic syndrome, cancer, cardiovascular diseases, and type 2 diabetes mellitus. In our study, we tested the possible antidiabetic effects of one of vitamin D3 analogs, alfacalcidol, solely or in a combination with metformin on type 2 diabetic rats. Type 2 diabetic model rats were induced by feeding high-fat diet for 4 weeks followed by intraperitoneal injection of streptozotocin. In addition to the control group, the diabetic rats were divided into four groups: untreated, metformin-treated, alfacalcidol-treated, and combination-treated group (metformin + alfacalcidol) for 4 weeks...

A female in her late teens purposely ingested alcohol fuel containing methanol to commit suicide, which she admitted on social media. She was found in distress by her parents and died at the hospital some hours later. Autopsy revealed swelling of the brain and edematous and congestive lungs. No other trauma or unusual findings were revealed at autopsy. Methanol was detected upon routine screening for alcohols by headspace gas chromatography with flame-ionization detection. To confirm the presence of methanol and its metabolite formic acid, a method with detection by mass spectrometry was used...

Peptidylarginine deiminases (PADs) are calcium dependent enzymes with physiological and pathophysiological roles conserved throughout phylogeny. PADs promote post-translational deimination of protein arginine to citrulline, altering the structure and function of target proteins. Deiminated proteins were detected in the early developmental stages of cod from 11 days post fertilisation to 70 days post hatching. Deiminated proteins were present in mucosal surfaces and in liver, pancreas, spleen, gut, muscle, brain and eye during early cod larval development...

We previously discovered that oral treatment with AC261066, a synthetic selective agonist for the retinoic acid β2-receptor (RARβ2), decreases oxidative stress in the liver, pancreas, and kidney of mice fed a high-fat diet (HFD). Since hyperlipidemic states are causally associated with myocardial ischemia and oxidative stress, we have now investigated the effects of AC261066 in an ex-vivo ischemia/reperfusion (I/R) injury model in hearts of two prototypic dysmetabolic mice. We found that a 6-week oral treatment with AC261066 in both genetically hypercholesterolemic (ApoE-/-) and obese (HFD-fed) wild-type mice exerts protective effects when their hearts are subsequently subjected to I/R ex vivo in the absence of added drug...

Cushing's syndrome (CS), including visceral obesity, dyslipidemia, hypertension and diabetes among its many manifestations, is "a model" of metabolic syndrome. Glucocorticoid (GC) excess, through a combination of effects on liver, muscle, adipose tissue and pancreas, increases gluconeogenesis and impairs insulin sensitivity, leading to carbohydrate abnormalities. Dyslipidemia is a common finding in CS as a consequence of GC-related increased lipolysis, lipogenesis and adipogenesis. CS patients experience typical changes in body composition, with fat redistribution resulting in accumulation of visceral adipose tissue...

Preclinical testing of anticancer therapies relies on relevant xenograft models that mimic the innate tendencies of cancer. Advantages of standard subcutaneous flank models include procedural ease and the ability to monitor tumor progression and response without invasive imaging. Such models are often inconsistent in translational clinical trials and have limited biologically relevant characteristics with low proclivity to produce metastasis, as there is a lack of a native microenvironment. In comparison, orthotopic xenograft models at native tumor sites have been shown to mimic the tumor microenvironment and replicate important disease characteristics such as distant metastatic spread...

Abdominal image segmentation is a challenging, yet important clinical problem. Variations in body size, position, and relative organ positions greatly complicate the segmentation process. Historically, multi-atlas methods have achieved leading results across imaging modalities and anatomical targets. However, deep learning is rapidly overtaking classical approaches for image segmentation. Recently, Zhou et al. showed that fully convolutional networks produce excellent results in abdominal organ segmentation of computed tomography (CT) scans...

Mucinous cystic neoplasms (MCNs) occur in the ovary, pancreas and retroperitoneum but very rarely in the liver. MCNs are known to harbor ovarian-like mesenchymal stroma (OLS) expressing progesterone- and estrogen receptors. In this study we evaluated steroidogenesis in OLS of 25 hepatic MCNs and 24 pancreatic MCNs. Both steroid receptors and steroidogenic factors were immunohistochemically evaluated using H-score and results were compared with those in 15 ovarian MCNs and 10 normal ovaries. Androgen receptor (AR) H-scores in OLS were significantly higher in hepatic, pancreatic and ovarian MCN than those in normal ovaries...
