Abstract
Objective To explore the causes of esophageal cancer (ESCC) and provide a theoretical basis for prevention and treatment of ESCC by analyzing dietary nutrients intake and other blood indicators of Kazakh patients with ESCC.Methods 198 ESCC cases and 200 controls were recruited in Xinjiang. The food frequency questionnaire was used to investigate the dietary nutrients intake. After collecting blood samples, the automated chemiluminescence immunoassay analyzer was applied to measure serum FA level and serum vitamin B12 level. The enzyme-linked immunosorbent assay was used to observe the serum DNMT1 level.Results The cholesterol intake of ESCC group was higher than that of the control group while the intakes of protein, thiamin, riboflavin, FA, vitamin A, B6, C and E were lower than the control group. Levels of serum FA and serum vitamin B12 in ESCC group were lower, while the serum DNMT1 level was higher.Conclusion Lacking fresh vegetables, low educational level, low income, alcoholism, eating solid and dry food and smoked meat, dieting irregularly, low serum FA level, high serum DNMT1 level were risky factors of ESCC for Kazakhs. The occurrence of ESCC reduced with the increase of serum FA but increased when serum DNMT1 increased.

Abstract
In the current study, in-situ formed Al/6wt. % TiB2 and Al/6wt. % TiB2/4wt. % Cu Metal Matrix were investigated. Composites were made using the sir casting method, and both composites were compared. The composite is synthesized by combining two precursor salts, Potassium Hexa Fluro Titanate (KBF4) and potassium tetrafluoroborate (K2TiF6), with stoichiometric compositions corresponding to 6 percent by weight of TiB2 particles, with A356 aluminium melt at 820° C, speed 300 rpm, and holding time 30 minutes. Following that, 4wt. % Cu powder was added to the composite melt, which was then poured into the permanent mould. Mechanical properties tests such as tensile strength, hardness, and fracture toughness were carried out in accordance with ASTM guidelines. The mechanical properties of the in-situ formed Al/6wt. % TiB2/4wt. % Cu composite outperform those of the Al/6wt.% TiB2 composite and base metal. Optical micrograph and XRD analysis both confirm the presence of TiB2 and Cu particles.

Abstract
Nanosize Nickel ferrite (NiF) was synthesized by the co-precipitation methods and its effect as a 5 % by mass additive was studied on the thermal decomposition of micrometer and nanometer size NTO. In the presence of 5 % NiF additive, the thermal decomposition peak temperature of NTO was decreased from 276.36 to 260.18 oC and that of nano NTO was decreased from 261.38 to 258.89 oC (β=10 oC min-1). The kinetics parameters confirms the catalytic activity of NiF for the thermal decomposition of NTO, and nNTO as the parameters such as activation energy (NTO=~25.45 % and nNTO=~45.94 % decrement), and pre-exponential factor (NTO=~21.94 % and nNTO=~43.12 % decrement) were decreased when 5 % NiF additive was added to NTO, and nNTO. The rate of the decomposition process was increased in the presence of 5 % NiF catalyst, indicating the faster thermal decomposition of both NTO, and nNTO in the presence of nickel catalyst.

Published: January 2022

Abstract
Due to the low cost and the scaling capability of Si substrate, InAlN/GaN high-electron-mobility transistors (HEMTs) on silicon substrate have attracted more and more attentions. In this paper, a high-performance 50-nm-gate-length InAlN/GaN HEMT on Si with a high on/off current (Ion/Ioff) ratio of 7.28 × 106, an average subthreshold swing (SS) of 72 mV/dec, a low drain-induced barrier lowing (DIBL) of 88 mV, an off-state three-terminal breakdown voltage (BVds) of 36 V, a current/power gain cutoff frequency (fT/fmax) of 140/215 GHz, and a Johnson’s figure-of-merit (JFOM) of 5.04 THz∙V is simultaneously demonstrated. The device extrinsic and intrinsic parameters are extracted using equivalent circuit model, which is verified by the good agreement between simulated and measured S-parameter values. Then the scaling behavior of InAlN/GaN HEMTs on Si is predicted using the extracted extrinsic and intrinsic parameters of devices with different gate lengths (Lg). It presents that a fT/fmax of 230/327 GHz can be achieved when Lg­ scales down to 20 nm with the technology developed in the study, and an improved fT/fmax of 320/535 GHz can be achieved on a 20-nm-gate-length InAlN/GaN HEMT with regrown ohmic contact technology and 30% decreased parasitic capacitance. This study confirms the feasibility of further improvement of InAlN/GaN HEMTs on Si for RF applications.

Published: January 2022

Abstract
Bacterial pathogens are a great threat to fish production. Gram-negative bacteria are among the major bacterial fish pathogens and zoonotic with the potential to infect humans. This cross-sectional study was conducted to isolate and identify major gram-negative bacteria from live and processed fish, and water samples from Lakes Hawassa, Langanoo and Ziway. A total of 674 different types of samples: 630 tissue samples (210 samples for each intestine, Kidney and liver collected from 210 live fish (Oreochromis niloticus, Cyprinus carpio and Clarias gariepinus), 20 processed fish samples from lake Ziway fish processing center and 24 lake water samples were included in the study from each lake. The mean values of pH, temperature, dissolved oxygen and nitrate in all water samples were within the normal range at which most freshwater fish species become non-stressed. Of a total of 674 samples included in the study, the bacteria were isolated from 154 (22.8%) samples with significant difference (P<0.05) observed in some isolates with respect to sample origin. Of these 154 isolates, 103(66.8%) isolates were gram-negative bacteria consisting of 15 species based on morphology and a range of biochemical tests. From live fish samples, Escherichia coli was the dominant species with 15 isolates followed by Edwardsiella tarda (12), Salmonella Paratyphi (10), Salmonella Typhi (9), Shigella dysenteriae(7), Shigella flexneri (7), Klebsiella pneumonia (7), Enterobacter aerogenes (6), Enterobacter cloacae (5), Pseudomonas aeruginosa (5), Vibrio parahemolyticus (5), Aeromonas sobria (4), Citrobacter freundii (4), Citrobacter koseri (4) and Plesiomonas shigelloides(3). Detection of common fecal coliforms (E. coli, K. pneumoniae and E. aerogenes) and Salmonella spp. in processed fish indicates the potential danger of passage of pathogenic bacteria and/or their poisons to humans via infected and/or contaminated fish products. Human infection by pathogenic fish bacteria and food poisoning is possible through contamination of fish product in fish production chain due to inadequate handling, poor hygiene and contact with contaminated water. Therefore, producers, consumers and all other stakeholders need to be cautious during handling, processing and consumption of fish harvested from the study lakes.

Abstract
BackgroundThe objectives of the present study were to investigate whether the expression of transferrin receptor 1 (TfR1), glucose transporter 1 (Glut1), or Cluster of Differentiation 98 Heavy Chain (CD98hc) is epigenetically regulated in brain capillary endothelial cells (BCECs) denoting the blood-brain barrier (BBB).MethodsThe expression of these targets was investigated both in vitro and in vivo following treatment with the histone deacetylase inhibitor (HDACi) valproic acid (VPA). Mice were injected intraperitoneally with VPA followed by analysis of isolated brain capillaries, and the capillary depleted brain samples. Brain tissue, isolated brain capillaries, and cultured primary endothelial cells were analyzed by RT-qPCR, immunolabeling and ELISA for expression of TfR1, Glut1 and CD98hc. We also studied the vascular targeting in VPA-treated mice injected with monoclonal anti-transferrin receptor (Ri7) conjugated with 1.4 nm gold nanoparticles. ResultsValidating the effects of VPA on gene transcription in BCECs, transcriptomic analysis identified 24,371 expressed genes, of which 305 were differentially expressed with 192 upregulated and 113 downregulated genes. In vitro using BCECs co-cultured with glial cells, the mRNA expression of Tfrc was significantly higher after VPA treatment for 6 h with its expression returning to baseline after 24 h. Conversely, the mRNA expression of Glut1 and Cd98hc was unaffected by VPA treatment. In vivo, the TfR1 protein expression in brain capillaries increased significantly after treatment with both 100 mg/kg and 400 mg/kg VPA. Conversely, VPA treatment did not increase GLUT1 or CD98hc. Using ICP-MS-based quantification, the brain uptake of nanogold conjugated anti-TfR1 antibodies was non-significant in spite of increased expression of TfR1. ConclusionsWe report that VPA treatment upregulates TfR1 at the BBB both in vivo and in vitro in isolated primary endothelial cells. In contrast, VPA treatment does not influence the expression of GLUT1 and CD98hc. The increase in the overall TfR1 protein expression however does not increase transport of TfR-targeted monoclonal antibody and indicates that targeted delivery using the transferrin receptor should aim for increased mobilization of already available transferrin receptor molecules to improve trafficking through the BBB.

Abstract
Background: The incidence of type 2 diabetes mellitus is increasing worldwide. The literature suggests that acupuncture is a possible complementary therapy for type 2 diabetes mellitus. This study aims to determine the effect of acupuncture as an adjunctive therapy on homeostasis model assessment-insulin resistance (HOMA-IR), adiposity and health-related quality of life (HRQOL) in patients with type 2 diabetes mellitus. Method and design: This randomised, double-blind, placebo controlled and parallel design trial will be carried out in three public university teaching hospitals in Malaysia. Eligible type 2 diabetes mellitus subjects will be randomly assigned to receive either acupuncture (n=30) or a placebo (n=30). The intervention is carried out using acupuncture ‘press’ needle on abdomen area (10 sessions of treatment), twice a week over 6 weeks. Both groups will continue with their routine diabetes care. Primary outcome of HOMA-IR and secondary outcomes of body mass index and waist circumference will be measured at the time of recruitment (baseline) and after completion of 10 sessions (week 7) of the treatment. Additionally, secondary outcome of HRQOL will be measured at the time of recruitment (baseline), after completion of 5 sessions (week 3/4) and 10 sessions (week 7) of the treatment. Any adverse event will be recorded at every visit.Discussion: The findings of this study will provide important clinical evidence for the effect of acupuncture as adjunctive therapy on HOMA-IR, adiposity and HRQOL of type 2 diabetes mellitus.

Published: January 2022

Abstract
Background: Papillary thyroid carcinoma (PTC) with squamous metaplasia is a relatively rare and special subtype adenocarcinoma of thyroid which involves multiple genetic changes. We reported a rare case of atypical PTC with squamous metaplasia and RET/NRAS/TERT/PIK3CA mutations which was confirmed after surgical resection pathologically. Case summary: A 2.5×2.5×2 cm3, smooth, hard, clear boundaries and solid nodule on the left thyroid gland was found on relevant physical examination of the patient. And then, the unilateral radical resection of thyroid carcinoma was performed after diagnosing. The tumor cells were squamous metaplasia and arranged in structures with diffuse growth pattern microscopically. At high magnification, stretched nucleus, nuclear grooves and internuclear pseudoinclusions in tumor cells were detected, and the follicular epithelium cells were atypical. Immunohistochemical staining shown strong positiveness of CK19, TTF-1, P40 and Galectin-3, partial positiveness of TG of tumor cells and negativeness of Calcitonin, which could exclude medullary thyroid carcinoma (MTC). Furthermore, first generation sequencing of 18 PTC related genes techniques shown RET, NRAS, TERT and PIK3CA was mutated. Conclusion: Genetic detection is vital to the diagnosis of thyroid adenocarcinoma, especially for the PTC with atypical morphology or rare metaplasia

Published: January 2022

Abstract
The most important welding processes used are the Gas Metal Arc (GMA) welding, the Tungsten Inert Gas (TIG) welding, and the Manual Metal Arc (MMA) welding processes. The goal of our investigation was to monitor the distribution of iron (Fe), manganese (Mn), calcium (Ca) and magnesium (Mg) in the lung, spleen, liver, and kidney of mice after inhalation exposure of different welding methods using different steel base materials. The treatment groups were the following: MMA-mild steel, MMA-molybdenum-manganese (MoMn) alloy, TIG-mild steel, and TIG-stainless steel. The samples were taken 24- and 96 hours after the treatments.Most importantly, it was found that the Mn concentration in the lung’ samples of the MMA-mild steel and the MMA-MoMn groups was increased extremely at both sampling times and in the spleen’ samples also. In the TIG groups, the rise of the Mn concentration was only considerable in the lungs and spleens at 24h, and emerged concentration was found in the liver in 96h samples. Histopathology demonstrated emerged siderin content in the spleens of the treated animals and in siderin filled macrophages in the lungs mostly in all treated groups. Traces of high-level glycogen retention was found in the MMA groups at both sampling times. Similar glycogen retention in TIG-Ms and TIG stainless group’s liver samples and emerged number of vacuoles, especially in the hepatocytes of the TIG-stainless steel 96h group were also found.The mentioned results raise the consequence that there is a considerable difference in the kinetics of the Mn distribution between the MMA- and the TIG-fume treated groups. Hence, the result suggests that manganese has a particle-size dependent toxico-kinetics property. The anomaly of the glycogen metabolism indicates the systemic effect of the welding fumes. Also, the numerous vacuoles mentioned above show a possible liver-specific adverse effect of some components of the TIG-stainless steel welding fumes.

Abstract
Anaphylaxis to fire ant venoms (Solenopsis sp) is a significant cause of systemic allergic reaction caused by Hymenoptera stings in children. There are only a few reports about the safety and efficacy of specific immunotherapy. We aim evaluate clinical characteristics, IgE and IgG4 specific responses of patients undergoing immunotherapy with a whole-body extract of Solenopsis sp after one year of the maintenance phase. Thirty-three patients were enrolled due to anaphylaxis by fire ant venom (Solenopsis sp) and underwent specific venom immunotherapy. They were assessed at baseline and one year after the beginning of the maintenance phase for skin test; specific IgE and IgG4 antibodies to fire ant venom; tryptase. All patients included presented a severe anaphylactic reaction. Although two patients (6.25%) presented a tryptase level higher than 11.4 ug/ml, systemic mastocytosis was ruled out. There was no relationship between the severity of the reaction with gender, tryptase level, atopy, previous reactions, concentration of the allergen in the skin test or specific IgE level. There was an increase of the specific IgG4/IgE ratio between the two time points. Reactions were local, with only two mild systemic reactions during the build-up phase. Twenty patients had accidental stings during immunotherapy, with 3 presenting only urticaria. This study is unprecedented in evaluating clinical and laboratory data in the fire ant immunotherapy. Our results show that after one year of the maintenance phase, patients did not develop any severe reaction with only a few mild reactions and presented a significant production of specific IgG4.
Uterine Rupture of a Patient With Rudimentary Horn Pregnancy at 26th Gestational Weeks Diagnosed via Magnetic Resonance Imaging: a Case Report
Authors: SARIKAYA SEVCAN , AYBAY MUHSİN NUH 
Published: January 2022

Abstract
Objective: Pregnancy of Rudimentary Horn is a type of ectopic pregnancy, that is recognized almost always during surgical treatment of a rupture of the rudimentary horn. This is an obstetric case diagnosed preoperatively by magnetic resonance imaging (MRI).Case: We report the case of a 19-years-old primigravida patient with rupture of rudimentary horn in 26th gestational week. The patient presented with sudden onset severe abdominal pain in the emergency room. Intraabdominal free fluid is detected. To evaluate the etiology of free fluid and location of the gestational sac, an abdominal magnetic resonance imaging (MRI) scan was planned. The decision of emergent laparotomy is made because of sonographic detection of abdominal excessive -concentrated- free fluid, abdominal tenderness, and 2 points decrease of hemoglobin value in the control hemogram. A rudimentary horn pregnancy and fundal rupture of the rudimentary part of the uterus are diagnosed during the surgical procedure. A baby -live- weighing 450 grams was delivered. The ruptured rudimentary horn and same-sided tuba uterina were surgically removed.Conclusion: Rudimentary horn pregnancy is a rare ectopic pregnancy. Diagnosis is difficult clinically, even with diagnostic imaging modalities. Identifying both cornuas systematically in all patients increases the detection rate. The absence of continuity between the gestational sac’s lumen and the cervical canal on imaging is an important finding. Due to the serious maternal and fetal complications, its detection at an early week may be life-saving.

Authors: Schofield Chris , Suarez Lori Edwards , Schofield Nathan 
Published: January 2022

Abstract
Background:
Patients with Persistent Physical Symptoms (PPS) may have chronic physical disorders such as diabetes, COPD, Crohn’s, MS and/or ongoing medically unexplained symptoms, and in either case there can be both physical and [psychiatric aetiologies combined. Such co-morbidity tends to be chronic and hard to manage in any healthcare setting and therefore frequent attendance in healthcare settings is present for these patients. We rolled out a primary care based integrated multidisciplinary liaison psychiatry team to 3 CCG areas in Nottinghamshire in October 2019 to see this patient group and have taken patient reported outcome measures from baseline up to 15 months later as part of normal service evaluation.
Results:
We show here that there are clinically relevant and statistically significant improvements in depressive symptoms (PHQ-9), anxiety symptoms (GAD-7) and physical symptoms (PHQ-15). The improvements in the EQ-5D-5L shows that in a whole health measure there are significant improvements over all and specifically in the anxiety/depression and usual activity domains.
Conclusion:
This is clinically very relevant especially when seen in the context that these results were achieved despite a pandemic affecting the whole population. This model is scalable and integrated providers should look to implement it.
