Patterns of blood pressure changes in patients with head and neck cancer receiving radiotherapy or chemo-radiotherapy at a tertiary cancer centre.

Background: To evaluate patterns of blood pressure (BP) changes in patients with head and neck cancer (HNC) receiving radiation (RT)/chemo-radiation (CRT) METHODS: This study included data collection, compilation, and analysis of 451 consecutive HNC patients who underwent RT/CRT.

Results: Out of 451 patients, 376 (82%) were male and 75 (18%) were female with a median age of 52 years. Patients receiving 3DCRT experienced greater fall in BP, including for SBP and MAP, compared to those receiving IMRT-IGRT.

Treatment of fish processing industry wastewater using hydrodynamic cavitational reactor with biodegradability improvement.

Water generated from the fish processing industry is contaminated with organic matter. This organic matter present in wastewater increases the biochemical oxygen demand (BOD) and chemical oxygen demand (COD). A new technology, hydrodynamic cavitation (HC) is used to deal with this wastewater produced in fish processing plants.

Operating and hydrodynamic characteristics of a reversed flow jet loop bioreactor (RFJLB) with ejector.

The hydrodynamic characteristics of RFJLB was studied with superficial liquid velocity (Ul), nozzle diameter (Dn) and nozzle height (Hn) in the range of 0.0293-0.094m/s, 17.

Extraction of pesticides, dioxin-like PCBs and PAHs in water based commodities using liquid-liquid microextraction and analysis by gas chromatography-mass spectrometry.

Water based samples such as flavored drinks, juices and drinking water may contain contaminants at ultra trace level belonging to different chemical classes. A novel, simple, low-cost and fast method was developed and validated for trace residue extraction of pesticides, dioxin-like PCBs and PAHs from water and water based samples followed by analysis through gas chromatography (GC) coupled with time-of-flight mass spectrometry (ToFMS). The extraction solvent type, volume; sample volume and other extraction conditions were optimized.

Dissipation and distribution behavior of azoxystrobin, carbendazim, and difenoconazole in pomegranate fruits.

The dissipation behavior and degradation kinetics of azoxystrobin, carbendazim, and difenoconazole in pomegranate are reported. Twenty fruits/hectare (5 kg) were collected at random, ensuring sample-to-sample relative standard deviation (RSD) within 20-25%. Each fruit was cut into eight equal portions, and two diagonal pieces per fruit were drawn and combined to constitute the laboratory sample, resulting in RSDs <6% (n = 6).

Reporting ethical processes in two Indian journals.

Background: In biomedical journals, authors are expected to report if the study was carried out in accordance with international and national ethical guidelines and inform readers if approval from ethics committee was obtained and if written informed consent was taken from the participant or legal guardian.

Aims: To determine the proportion of research manuscripts in two pediatric journals published from India reporting on ethical clearance, obtaining of informed consent and/or assent.

Settings And Design: Retrospective study for analysis of research articles published.
