Postoperative chylous ascites successfully managed by selective lymphatic embolization: Case report and literature review.

Postoperative chylous ascites is a rare complication following retroperitoneal surgeries, presenting significant challenges in diagnosis and management. Retroperitoneal cyst surgery resulting in chylous leaks is an uncommon complication that has not been previously reported in the literature. Therefore, we report a clinical case of postoperative chylous ascites following retroperitoneal cyst removal with underlying idiopathic thoracic duct obstruction.

MDM2 up-regulates the energy metabolism in NSCLC in a p53-independent manner.

Although an E3 ligase MDM2 is the major negative regulator of the p53 tumor suppressor, a growing body of evidence suggests its p53-independent oncogenic properties. In particular, MDM2 has been shown to regulate serine metabolism independently of p53 status in several types of neoplasia, including NSCLC. Using the GSEA approach and publicly available molecular data on NSCLC tumors, our bioinformatics data suggest that MDM2 affects a number of metabolic genes, particularly those encoding components of the electron transport chain (ETC).

Agricultural wastes rich in β-mannan are an important environmental problem in tropical and sub-tropical countries. This research aims at dealing with this and investigates the valorization of mannan-rich copra meal from virgin coconut oil manufacturing into mannan-oligosaccharides (β-MOS) by enzymatic hydrolysis using β-mannanase from Bacillus licheniformis (BlMan26B). Lab-scale process, involving pre-treatment and bioconversion steps, were conducted and evaluated.

Intravenous misplacement of the nephrostomy catheter following percutaneous nephrolithotomy: A case report and review of 26 cases in the literature.

Intravenous misplacement of the nephrostomy catheter following percutaneous nephrolithotomy (PCNL) is severe and extremely rare, and little information is available about this complication. Because the patient's prognosis may be poor, sufficient attention should be paid to early identification and treatment of this complication. We report a case with intravenous misplacement of nephrostomy catheter and severe bleeding from the catheter after PCNL was transferred to our hospital.

Generalized lymphangiomatosis in patients treated for chylothorax following thoracoscopic sympathectomy: Case report.

Generalized lymphangiomatosis (GLA) is a very rare condition in adults, characterized by diffused proliferation of lymphatic vessels that requires differential diagnosis from other vascular disorders such as cavernous or capillary hemangioma. This is because of overlapping characteristics on histopathological examination. Therefore, imaging features such as CT and MRI are useful to evaluate morphological characteristics, location, and the extent of the spread as well as differential diagnosis with other pathologies.

Identification of Interleukin (IL)-33 Inhibitory Constituents from Pods.

Interleukin (IL)-33, a member of the IL-1 cytokine family, plays a vital role in immune system regulation and inflammation, with oxidative stress being implicated in its expression. During the search for compounds from natural sources with potential as therapeutic agents for allergic diseases via IL-33 signal modulation, we discovered significant IL-33 inhibitory activity in the methanol extract of (sword bean) pods. Through chromatographic separation and liquid chromatography-mass spectrometry, we isolated 11 compounds (-) from the methanol extract.

Arteriovenous malformation in the kidney allograft: A rare cause of hematuria in the post-transplant patient.

Gross hematuria is one of the most common complications in postrenal transplant patients, accounting for 12% of all renal recipients. The management plan in these cases varies depending on different entities, including infection, renal cell carcinoma, chronic graft rejection, kidney calculus, or recurrence of primary disease. On the other hand, vascular malformation like arteriovenous malformation was less likely to be mentioned due to a lack of consensus in the natural history, pathogenesis, and current management.

New diterpene lactone derivatives from leaves inhibit nitric oxide production in RAW 264.7 cells.

Phytochemical studies on plants have attracted considerable attention over the past few decades due to the structural diversities and significant biological activities of terpenoids produced by these plants.
