The feasibility of ammonia pre-separation during the thermal-alkaline pretreatment (TAP) of waste activated sludge was evaluated to mitigate ammonia inhibition during high solid anaerobic digestion (HSAD). The results showed that the TAP increased the organics hydrolysis rate as much as 77% compared to the thermal hydrolysis pretreatment (THP). The production and separation of the ammonia during the TAP exhibited a linear relationship with the hydrolysis of organics and the Emerson model. The pre-separation ratio of the free ammonia nitrogen exceeded 98...

A neurological basis for the fast fibre shift and atrophy seen in limb muscle of patients with chronic obstructive pulmonary disease (COPD) has not been considered previously. The objective of our study was: (i) to determine if denervation contributes to fast fibre shift and muscle atrophy in COPD; and (ii) to assess using a preclinical smoking mouse model whether chronic tobacco smoke (TS) exposure could initiate denervation by causing neuromuscular junction (NMJ) degeneration. Vastus lateralis muscle biopsies were obtained from severe COPD patients (n = 10 with low fat free mass index [FFMI], 65 y; n = 15 normal FFMI, 65 y) and healthy age- and activity-matched non-smoker control subjects (CON; n = 11, 67 y), to evaluate morphological and transcriptional markers of denervation...

OBJECTIVE: Present in silico study was carried out to explore the mode of inhibition of Leishmania donovani dihydrofolate reductase-thymidylate synthase (Ld DHFR-TS) enzyme by Withaferin-A, a withanolide isolated from Withania somnifera. Withaferin-A (WA) is known for its profound multifaceted properties, but its antileishmanial activity is not well understood. The parasite's DHFR-TS enzyme is diverse from its mammalian host and could be a potential drug target in parasites. RESULTS: A 3D model of Ld DHFR-TS enzyme was built and verified using Ramachandran plot and SAVES tools...

As of date the two temperature sensitive mutations isolated in pheST operon include pheS5 (G293 →A293 ) and pheT354. Recently, we reported that G673 of pheS defines a hot spot for intragenic suppressors of pheS5. In this investigation, in 13 independent experiments, a collection of temperature sensitive mutants were isolated by localized mutagenesis. Complementation using clones bearing pheS+ , pheT+ , and pheS+ T+ indicated that 34 mutants could harbor lesion(s) in pheS and four could be in pheT and one mutant might be a double mutant...

OBJECTIVE: In 2013, our group assessed a risk stratification tool of endometrial cancer (EC), called REM (Risk of Endometrial Malignancy). A well known risk factor for EC is body mass index (BMI). In fact, (BMI > 30 and <35 kg/m2) and severe obesity (BMI > 35 kg/m2) were associated with a 2.6-fold and a 4.7-fold increase in EC risk, respectively. Therefore, in the present study we aim to improve the performance of REM, including BMI and developing a new scoring system, called REM-B (Risk of Endometrial Malignancy score associated to BMI), to classify patients into high risk or low risk groups for EC...

To evaluate the role of constitutive epigenetic changes in normal body cells of BRCA1/BRCA2-mutation negative patients, we have developed a deep bisulfite sequencing assay targeting the promoter regions of 8 tumor suppressor (TS) genes (BRCA1, BRCA2, RAD51C, ATM, PTEN, TP53, MLH1, RB1) and the estrogene receptor gene (ESR1), which plays a role in tumor progression. We analyzed blood samples of two breast cancer (BC) cohorts with early onset (EO) and high risk (HR) for a heterozygous mutation, respectively, along with age-matched controls...

REVIEW
Tiago V Maia, Vasco A Conceição
Tourette syndrome (TS) is thought to involve dopaminergic disturbances, but the nature of those disturbances remains controversial. Existing hypotheses suggest that TS involves 1) supersensitive dopamine receptors, 2) overactive dopamine transporters that cause low tonic but high phasic dopamine, 3) presynaptic dysfunction in dopamine neurons, or 4) dopaminergic hyperinnervation. We review evidence that contradicts the first two hypotheses; we also note that the last two hypotheses have traditionally been considered too narrowly, explaining only small subsets of findings...

Taro stalks (TS) were modified by diethylenetriamine (DETA) to obtain the modified taro stalks adsorbents (recorded as MTSA). This kind of raw material is unprecedented and the method of modification is relatively simple. The physicochemical properties of MTSA were characterized by scanning electron microscope (SEM), FTIR, and zeta potential analyzer. The capacity of MTSA for adsorbing heavy metals under different influencing factors was tested by UV-visible spectrophotometer. The results indicated that the gaps between the microspheres of MTSA are more, which are conducive to adsorption...

Helium ion beam lithography (HIL) is an emerging nanofabrication technique. It benefits from a reduced interaction volume compared to that of an electron beam of similar energy, and hence reduced long-range scattering (proximity effect), higher resist sensitivity and potentially higher resolution. Furthermore, the small angular spread of the helium ion beam gives rise to a large depth of field. This should enable patterning on tilted and curved surfaces without the need of any additional adjustments, such as laser-auto focus...

Asymmetrical septal occluder device (ASOD) has made percutaneous closure of ventricular septal defect an easy and effective management option. Although there are reports of aortic and tricuspid valvular regurgitation after deployment of ASOD, only few cases of tricuspid stenosis (TS) has been reported so far in the literature. We report a case of malaligned ASOD that occurred after successful device closure resulting in TS along with mild tricuspid and aortic regurgitation requiring surgical retrieval. Transesophageal echocardiography played crucial role in detecting the cause of tricuspid valve dysfunction besides providing continuous monitoring during the procedure...

Ammonia (NH3 ) volatilization is one of the primary pathways of nitrogen (N) loss from soils after chemical fertilizer is applied, especially from the alkaline soils in Northern China, which results in lower efficiency for chemical fertilizers. Therefore, we conducted an incubation experiment using an alkaline soil from Tianjin (pH8.37-8.43) to evaluate the suppression effect of Trichoderma viride (T. viride) biofertilizer on NH3 volatilization, and compared the differences in microbial community structure among all samples...

Lung cancer is the leading cause of cancer-related death worldwide; tobacco smoke (TS) constitutes the main causes of lung cancer. Acquisition of cancer stem cells (CSCs)-like properties is the essential progression for the initiation of lung cancer. However, the mechanisms for tobacco smoke-induced lung carcinogenesis remain elusive. In the present study, we demonstrated that long-term exposure of human bronchial epithelial (HBE) cells to TS resulted in malignant transformation and acquisition of CSC-like properties...
