Abstract

It was necessary to research an efficient treatment process suitable for township domestic wastewater. In this paper, the performance of the cyclic activated sludge system (CASS) system for simultaneous carbon (C), nitrogen (N) and phosphorus (P) removal was investigated by changing the operation cycle of the CASS reactor. Four operating conditions were set up, T1, T2, T3 and T4, with cycle times of 6, 8, 12 and 8 h (with carbon source), respectively. The results showed that the CASS system had good simultaneous removal of C, N and P. The highest removal rates of COD, TN, NH4+ -N and TP were 87.69, 72.99, 98.60 and 98.38%, respectively, at a cycle time of 8 h. The TN removal rate could be increased to 82.51% after the addition of carbon source. Microbial community analysis showed that Proteobacteria, Bacteroidetes and Candidatus Saccharibacteria were the main phylum-level bacteria. Their presence facilitated the effectiveness of the CASS process for nitrogen removal and phosphorus removal. Functional analysis of genes revealed that the abundance values of genes associated with C, N and P metabolism were higher when the treatment was effective.

Published: October 2023

Background:
Excessive insulin is the leading cause of metabolic syndromes besides hyperinsulinemia.
Insulin-lowering therapeutic peptides have been poorly studied and warrant urgent
attention.

Objective:
The main purpose of this study, was to introduce a novel peptide COX52-69 that was initially
isolated from the porcine small intestine and possessed the ability to inhibit insulin secretion
under high-glucose conditions by modulating large conductance Ca2+-activated K+ channels (BK
channels) activity.

Methods and Results:
Enzyme-linked immunosorbent assay results indicate that COX52-69 supressed
insulin release induced by high glucose levels in pancreatic islets and animal models. Furthermore,
electrophysiological data demonstrated that COX52-69 can increase BK channel currents
and hyperpolarize cell membranes. Thus, cell excitability decreased, corresponding to a reduction
in insulin secretion.

Conclusion:
Our study provides a novel approach to modulate high glucose-stimulated insulin secretion
in patients with hyperinsulinemia.
Relationship of Body Composition and PMS Symptoms: A Systematic
Review
Authors: Farpour Samaneh , Moradinazar Mehdi , Samadi Mehnoosh 
Published: October 2023

Aims:
Recent studies show that body composition is one of the most important factors
in the menstrual cycle. The purpose of this study is to investigate more comprehensively the effect
of body composition and anthropometric indicators on the symptoms of premenstrual syndrome
(PMS).

Materials and Methods:
This study is a secondary study that is considered a systematic review according to the implementation method. The statistical population is all the studies that have dealt
with the issue of the effect of anthropometric indicators on PMS from different aspects.

Results:
The final synthesis was performed on 7 articles after screening the studies. The synthesis
of articles related to the relationship between anthropometric indicators on PMS showed that
47.8% of women in the world have PMS, with the highest prevalence being reported in Iran at
98%. Studies have shown that the incidence of PMS, increased appetite, and weight gain in women with a BMI greater than 25 kg / m2
is more common. Weight gain causes endocrine disorders
that lead secretion of more sex hormones in obese or overweight women, which in turn leads to
the symptoms of PMS. Studies have shown a direct and significant relationship between PMS
symptoms waist circumference (WC), waist-to-height ratio (WTHR), and waist-to-hip ratio
(WHR), which according to the results, more central fat mass in women causes more severe symptoms of this syndrome. Also, studies showed that the risk of depression and anxiety in women
with PMS with a higher BMI and body fat mass is higher.

Conclusion:
Weight control and improvement of eating habits, can be effective in reducing the incidence of PMS symptoms. Furthermore, the high prevalence of PMS in studies requires further investigation and principled interventions with regard to physical and mental factors in this period.

Published: October 2023

Abstract:
The recent outbreaks of Nipah viral infection were associated with severe respiratory illness,
lethal encephalitis, and an extremely high mortality rate. As there are no approved antiviral
medications, patients with NiV infections are currently treated with repurposed or investigational
antivirals and supportive care. This review examines the potential health benefits of N. sativa in the
treatment of NiV infection. To identify relevant studies, the literature was searched in online databases
like Medline/PubMed, Google Scholar, Science Direct, and reference lists. Through its antiviral,
anti-inflammatory, antioxidant, anticonvulsant, immunomodulatory, bronchodilatory, and other
properties, a number of studies have demonstrated that N. sativa is effective against a variety of viral
infections, inflammatory conditions, neurological and respiratory illnesses, and other conditions. As a
result, in the treatment of NiV-infected patients, N. sativa could be added as an adjuvant treatment
alongside repurposed or investigational antivirals and supportive care. The efficacy of N. sativa in the
treatment of NiV infection will be determined by the results of upcoming randomized controlled clinical
trials.

Authors: Panjaitan Amos Ruben , Pasaribu Arsen Nahum 
Published: October 2023

Memes have become a unique way of conveying messages and sharing experiences in today's social media era. The FIFA World Cup is one of the biggest sporting tournaments in the world, and its audience, which is divided into various regions and circles, has attracted researchers to make it an object. The aims of this semiotic analysis study are to determine the signifier and the signified, as well as the denotation and connotation, as well as the meaning of FIFA World Cup Qatar 2022 memes. The descriptive qualitative method is being used in the study. To analyze the data, the researchers applied Roland Barthes' theory. Memes are classified as signifiers and signified, which can be expressed verbally or visually. The researchers also explained the denotative and connotative interpretations of the 2022 FIFA World Cup in Qatar. The writers selected four memes for this analysis that talked about watching experiences, trolling the fans and players, and giving thoughts about the FIFA World Cup 2022 Qatar tournament. The results show that the signifiers in the memes were very random and unique, such as the heartbeat display in the first image, scientists in the second image, actors in the third image, scientists, and cartoon characters with flags in the last image. These signs certainly have objective or literal meanings (denotation) and subjective or other meanings (connotation). Most of the connotational meaning from memes that have been analyzed focuses on sharing the experience of watching the FIFA World Cup 2022 competition and also trolling the football supporters or even the players that participated

Published: October 2023

The aim of this study is to review polyether ether ketone (PEEK), its characteristics and use in prosthodontics. Polyetheretherketone (PEEK) is one of the most used semi-crystalline thermoplastic polymers in aeronautics and aerospace. This new material matches the technological advancements and patient's desires for a natural and aesthetic look, thanks to its strength, superior biocompatibility, low plaque affinity and aesthetics characteristics close to the desired natural dental structure. PEEK has good mechanical and electrical properties such as resistance to high temperature and resistance to hydrolysis. Satisfactory findings have also been observed when used in knee, hip, spine and other implants.
PEEK polymer is suitable to use in prosthodontics. PEEK can fulfil the long-term demand of an ideal multipurpose material for biomedical applications. However, there are not enough statements about complications, biofilm formation on PEEK surface and its resistance to compression. More research should be done to find out the results.
