The Agrilus wittemani species-group comprising six species from South and Southeast Asia; two of these are endemic to south India. Four new species of A. wittemani species-group Jendek & Nakládal, 2017 are described in this paper: Agrilus keralensis Seena, Anand and Shibu-Vardhanan sp. nov.; A. palakkadensis Seena, Anand and Shibu-Vardhanan sp. nov.; Agrilus sahyadriensis Seena, Anand and Shibu-Vardhanan sp. nov.; A. silentvalleyensis Seena, Anand and Shibu-Vardhanan sp. nov. A key to all species is provided and complemented with illustra tions of habitus and genitalia.

Obesity is generally associated with low-grade chronic inflammation that involves the recruitment of macrophages and other inflammation factors to the adipocytes of obese individuals. Tumor necrosis factor-alpha (TNF-α), a cytokine associated with systemic inflammation, is elevated in conditions of obesity. TNF-α is an important factor that plays an important role in skeletal muscle wasting. Apoptosis of myonuclei contributes to the loss of muscle mass and therefore plays an important role in skeletal muscle atrophy. In mouse models that were fed a high fat diet (HFD), a lipolysis-stimulating peptide-VHVV (purified from hydrolysate resulting from flavourzyme treatment of soy protein) was found to reduce HFD-related apoptotic effects in mice skeletal muscle and potentially control atrophy. HFD fed mice had heavier body weight than those fed with normal chow, and VHVV administration restricted lipid accumulation in muscle tissues of mice fed with HFD but increased nutrient uptake. Moreover, specific concentrations of VHVV regulated TNF-α expression that was elevated by HFD, suppressed apoptosis-related proteins and regulated the proteins of lipid metabolism.
A Ripple Rejection Inherited RPWM for VSI Working with Fluctuating DC Link Voltage

A two stage ac drive configuration consisting of a single-phase line commutated rectifier and a three-phase voltage source inverter (VSI) is very common in low and medium power applications. The deterministic pulse width modulation (PWM) methods like sinusoidal PWM (SPWM) could not be considered as an ideal choice for modern drives since they result mechanical vibration and acoustic noise, and limit the application scope. This is due to the incapability of the deterministic PWM strategies in sprawling the harmonic power. The random PWM (RPWM) approaches could solve this issue by creating continuous harmonic profile instead of discrete clusters of dominant harmonics. Insufficient filtering at dc link results in the amplitude distortion of the input dc voltage to the VSI and has the most significant impact on the spectral errors (difference between theoretical and practical spectra). It is obvious that the sprawling effect of RPWM undoubtedly influenced by input fluctuation and the discrete harmonic clusters may reappear. The influence of dc link fluctuation on harmonics and their spreading effect in the VSI remains invalidated. A case study is done with four different filter capacitor values in this paper and results are compared with the constant dc input operation. This paper also proposes an ingenious RPWM, a ripple dosed sinusoidal referencerandom carrier PWM (RDSRRCPWM), which has the innate capacity of suppressing the effect of input fluctuation in the output than the other modern PWM methods. MATLAB based simulation study reveals the fundamental component, total harmonic distortion (THD) and harmonic spread factor (HSF) for various modulation indices. The non-ideal dc link is managed well with the developed RDSRRCPWM applied to the VSI and tested in a proto type VSI using the field programmable gate array (FPGA).

Background: Evaluate morbidities and “quality” of fiducial marker placement in primary liver tumours (hepatocellular carcinoma [HCC]) for CyberKnife. Materials and Methods: Thirty-six HCC with portal vein thrombosis (PVT) were evaluated for “quality” of fiducial placement, placement time, pain score, complications, recovery time and factors influencing placement. Results: One hundred eight fiducials were placed in 36 patients. Fiducial placement radiation oncologist score was “good” in 24 (67%), “fair” in 4 (11%), and “poor” in 3 (8%) patients. Concordance with radiologist score in “poor”, “fair”, and “good” score was 2/2 (100%), 4/5 (80%), and 24/27 (89%), respectively (p=0.001). Child-Pugh score (p=0.080), performance status (PS) (p=0.014) and accrued during “learning curve” (p=0.013) affected placement score. Mean placement time (p=0.055), recovery time (p=0.025) was longer and higher major complications (p=0.009) with poor PS. Liver segment involved (p=0.484) and the Barcelona Clinic Liver Cancer (BCLC) stage did not influence placement score. “Good” placement score was 30% in first cohort whereas 93% in last cohort (p=0.023). Time for placement was 42.2 and 14.3 minutes, respectively (p=0.069). Post-fiducial pain score 0-1 in 26 patients (72%) and pain score 3-4 was in 2 (6%). Five patients (14%) admitted in “day-care” (2 mild pneumothorax, 3 pain). Mortality in 1 patient (3%) admitted for hemothorax. Conclusion: Fiducial placement is safe and in experienced hands, “quality” of placement is “good” in majority. Major complications and admission after fiducial placement are rare. Complications, fiducial placement time, recovery time is more during the “learning curve”. Poor Child-Pugh score, extensive liver involvement, poor PS have higher probability of complications.
