Photocatalysis has attracted wide attention in eliminating volatile organic compounds (VOCs). This paper pays attention to the relationship between structure and performance of photocatalysts based on the fact that catalytic reactions arise on the surface of catalysts and the interface structure of photocatalysts plays key role in transfer efficiency of charges carriers. This review summarizes various surface/interface designs including unsaturated coordination such as oxygen vacancies, surface halogenations, and heterojunctions, homojunctions, facets, etc., as well as the application in photocatalytic degradation of VOCs. This paper reviews the influence of surface and interface properties of materials on VOCs molecules, effective strategies to promote the decomposition of VOCs from the perspectives of VOCs activation, reaction barrier etc., and presents various methods of photocatalyst design appropriately. The degradation path of highly toxic benzene VOCs are also summarized. In addition, the possible problems and suggestions for photocatalytic degradation of VOCs are proposed.This review is focused on new electrophoretic deposition (EPD) mechanisms for deposition biomacromolecules, such as biopolymers, proteins and enzymes. Among the rich literature sources of EPD of biopolymers, proteins and enzymes for biomedical applications we selected papers describing new fundamental deposition mechanisms. Such deposition mechanisms are of critical importance for further development of EPD method and its emerging biomedical applications. Our goal is to emphasize innovative ideas which have enriched colloid and interface science of EPD during recent years. We describe various mechanisms of cathodic and anodic EPD of charged biopolymers. Special attention is focused on in-situ chemical modification of biopolymers and crosslinking techniques. Recent innovations in the development of natural and biocompatible charged surfactants and film forming agents are outlined. Among the important advances in this area are the applications of bile acids and salts for EPD of neutral polymers. Such innovations allowed for the successful EPD of various electrically neutral functional polymers for biomedical applications. Particularly important are biosurfactant-polymer interactions, which facilitate dissolution, dispersion, charging, electrophoretic transport and deposit formation. Recent advances in EPD mechanisms addressed the problem of EPD of proteins and enzymes related to their charge reversal at the electrode surface. Conceptually new methods are described, which are based on the use of biopolymer complexes with metal ions, proteins, enzymes and other biomolecules. This review describes new developments in co-deposition of biomacromolecules and future trends in the development of new EPD mechanisms and strategies for biomedical applications.Although eutrophic urban rivers receiving loads of wastewater represent an important anthropogenic source of N2O, little is known as to how temperature and other environmental factors affect temporal variations in N2O emissions from wastewater treatment plants (WWTPs) and downstream rivers. Two-year monitoring at a WWTP and five river sites was complemented with available water quality data, laboratory incubations, and stable isotopes in N2O and NO3- to explore how wastewater effluents interact with seasonal changes in environmental conditions to affect downstream metabolic processes and N2O emissions from the lower Han River traversing the megacity Seoul. Water quality data from four WWTPs revealed significant inverse relationships between water temperature and the concentrations or fluxes of total N (TN) in effluents. Fasudil Increased TN fluxes at low temperatures concurred with N2O surges in WWTP effluents and downstream rivers, counteracting the long-term decline in TN fluxes resulting from enhanced wastewater treatments. Incubation experiments with river water and sediment, in isolation or combined, implied the hypoxic winter sediment as a large source of N2O, whereas the anoxic summer sediment produced a smaller amount of N2O only when it was added with oxic water. For both WWTP effluents and downstream rivers, bulk isotope ratios and intramolecular distribution of 15N in N2O distinctly differed between summer and winter, indicating incomplete denitrification in the hypoxic sediment at low temperatures as a primary downstream source adding to WWTP-derived N2O. Winter surges in wastewater TN and sediment N2O release highlight temperature variability as an underappreciated control over anthropogenic N2O emissions from increasingly urbanized river systems worldwide.
Rhabdomyosarcoma (RMS) is the malignant tumor of skeletal muscles that origin from rhabdomyoblast. RMS is the most common soft tissue tumor in children, but this is a sporadic condition in adults and only 1% of any solid malignancies of an adult. The most prevalent subtype of RMS in an adult is a pleomorphic type.

We reported a case of a 57 years old woman with swelling on the left chest with pain for three years. Physical examination revealed swelling on the left chest with solid consistency and immobile. The thorax CT-scan with IV contrast suspicious soft tissue tumor on the anteromedial of the left chest wall that stuck to the left lung.

Histopathological examination confirmed the pleomorphic subtype of rhabdomyosarcoma. The interdisciplinary idea was reported to be superior to a single therapeutic modality. The patient underwent an incisional biopsy.

This is a case of pleomorphic rhabdomyosarcoma diagnosed base on histopathology from an incisional biopsy, and IHC performed wide excision gave satisfactory results.

Lymphangioma is an abnormal proliferation of lymphatic vessels. Isolated splenic lymphangioma (SL) is rare; in the last 30 years only 22 cases were reported in the literature. Diagnosis is difficult by the absence of typical symptoms and signs. SL is often asymptomatic and occasionally detected through radiological exams or, after the onset of a life-threatening complication, at surgery or pathological examination. Surgery represents the treatment of choice.

A 22-year-old Caucasian male was admitted to the Emergency Department after a car accident, complaining of sudden onset, severe, left upper quadrant abdominal pain. Abdominal examination revealed mild abdominal distention and a severe abdominal pain on superficial and deep palpation of left upper abdominal quadrant with obvious muscle guarding and rebound tenderness. Abdominal computed tomography scan showed splenic rupture with hemoperitoneum. Laboratory tests reported severe anemia. The patient received blood transfusions and was taken emergently to the operating room for exploratory laparotomy, evacuation of hemoperitoneum and splenectomy.
