Addressing the challenges of missed parathyroid glands in ultrasonography for secondary hyperparathyroidism: a retrospective observational study.

Purpose: Preoperative localization plays an important role in secondary hyperparathyroidism (SHPT) surgery. The advantages of neck ultrasound (US) include high availability and low cost. However, the reported sensitivity of US is 54%-76%, and the reason for missed parathyroid glands (PGs) on US has been rarely addressed.

Nitrogen removal strategy for real swine wastewater by combining partial nitrification-denitrification process with anammox.

Anammox process offers reduced operational cost and energy requirement compared to nitrification-denitrification methods due to lower biomass generation and no need for external carbon sources and aeration. High ammonia concetration and low biodegradable anaerobic digester of swaine wastewater provided an advantage for the growth of anammox microorangism. An anoxic/oxic (A/O) SBR and an anammox SBR were implemented parallelly to treat the same swine wastewater with partial nitrification/denitrification and partial nitrification/anammox process, respectively, and to compare their nitrogen removal efficiency.

Molecular Necklaces Formed Through Zn-Templated Binding of Macrocycles with Dynamically Formed Imines as Guest Recognition Sites.

Herein we demonstrate an "in-ring establishing" strategy for assembling interlocked molecules through dynamic imine formation, "establishing" the host recognition sites in situ. Using Zn ions to template the assembly of a pyridine-containing macrocycle with semidumbbell-shaped triazole-containing aldehyde and amine derivatives, we obtained the corresponding [2]rotaxane in high yield (85 %) after subsequent imine reduction (NaBH) and amine protonation (NHPF). We performed the same three steps (assembly, reduction, protonation) to prepare a stable and highly symmetrical [5]molecular necklace ([5]MN) from 12 components (two almost-90°-oriented dialdehydes, two almost-90°-oriented diamines, four macrocycles, four Zn ions) in an overall yield of 69 %.

Performances of full-scale biological nitrogen pre-treatment process for drinking water source: Seasonal variations and microbial community.

This study investigated the performance of the full-scale unit over a two-year period to enhance nitrification efficiency and provide operational strategies. Results indicated that raw water quality from Donggan River was notably influenced by seasonal variations, particularly during dry and wet seasons, impacting the nitrification efficiency of the biological pretreatment process. Factors such as influent concentrations of ammonia and total Kjeldahl nitrogen were found to have significant effects on nitrification, with temperature and conductivity also showing correlations.

Biological treatment of N-methylpyrrolidone, cyclopentanone, and diethylene glycol monobutyl ether distilled residues and their effects on nitrogen removal in a full-scale wastewater treatment plant.

Recycle and reuse of these solvents produce distillate residues and require treatment before being discharged. This study aimed to evaluate the performance of the biological treatment system in a full-scale wastewater treatment plant that treats wastewater containing distillate residues from the recycling of electronic chemicals.

Preoperative work-up and results of parathyroidectomy plus auto-transplantation for the elderly with secondary hyperparathyroidism.

Background: Total parathyroidectomy for secondary hyperparathyroidism has low morbidity and mortality rates and requires a special workup in the preoperative period.

Methods: Neck echography and technetium-99m-sestamibi scintigraphy were performed preoperatively. Cardiac echography, a thallium-201 myocardial perfusion scan, and cardiac catheterization were performed if necessary.

Combination of treatments with transoral endoscopic thyroidectomy vestibular approach (TOETVA) for Graves' disease.

Although the success rates of non-surgical treatments for Graves' disease such as antithyroid medication and radioiodine ablation were good, there were still failure of treatments or intolerance for some patients. Traditional thyroid surgery could treat these patients but result in unaesthetic neck scars. Herein, we report the preliminary results of our combination of treatments with the transoral endoscopic thyroidectomy vestibular approach for Graves' disease.

Impact of Thyroid Incidentaloma on Liver Transplant: A Study of 1010 Recipients at a Single Center.

BACKGROUND Thyroid incidentalomas are typically nonpalpable thyroid nodules discovered during radiographic evaluation for a non-thyroid issue. Thyroid incidentalomas visualized by computed tomography (CT) and ¹⁸F-flurodeoxyglucose (FDG) positron emission tomography (PET) before living donor liver transplantation (LDLT) are rare. The aim of the study was to analyze the clinical impact of thyroid incidentalomas discovered prior to transplantation.

Preoperative ALBI grade predicts the outcomes in non-B non-C HCC patients undergoing primary curative resection.

Background: The albumin-bilirubin (ALBI) grade has been validated as a significant prognostic predictor for hepatocellular carcinoma (HCC). However, there is little information about the ALBI grade in patients with non-B non-C HCC (NBNC-HCC) receiving surgery.

Aim: This study aimed to evaluate the prognostic significance of the ALBI grade in patients with NBNC-HCC after primary curative resection.

Biological treatment of volatile organic compounds (VOCs)-containing wastewaters from wet scrubbers in semiconductor industry.

This study investigated biological treatment for two kinds of volatile organic compounds (VOCs)-containing wastewaters collected from wet scrubbers in a semiconductor industry. Batch test results indicated that one wastewater containing highly volatile organic compounds was not suitable for aerated treatment conditions while the other containing much lower volatile organic compounds was suitable for aerobic treatment. Accordingly, two moving bed bioreactors, by adding commercial biocarrier BioNET, were operated under aerobic and anoxic conditions for treating low volatility wastewater (LVW) and high volatility wastewater (HVW), respectively.

Can Microscopic Biliary Reconstruction Reduce Biliary Complication Rate in ABO-Incompatible Adult Living Donor Liver Transplantation?

BACKGROUND With the introduction of rituximab, ABO-incompatible (ABOi) living donor liver transplantation (LDLT) has been considered a feasible and safe procedure to overcome the shortage of organ donors. However, higher biliary complication rates remain an unresolved problem in the ABOi group. In our center, biliary anastomosis has been done with microscopic biliary reconstruction (MBR), which effectively reduced the biliary complication rate.

Reduced Expression of Metallothionein-I/II in Renal Proximal Tubules Is Associated with Advanced Chronic Kidney Disease.

Chronic kidney disease (CKD) is a commonly occurring complex renal syndrome that causes overall mortality in many diseases. The clinical manifestations of CKD include renal tubulointerstitial fibrosis and loss of renal function. Metallothionein-I/II (MT-I/II) is potentially expressed in the liver and kidney, and possesses antioxidant and metal detoxification properties.

The Role of Protease-Activated Receptor 2 in Hepatocellular Carcinoma after Hepatectomy.

: Protease activated receptor-2 (PAR2) is elevated in a variety of cancers and has been promoted as a potential therapeutic target. However, the clinical and prognostic values of PAR2 in hepatocellular carcinoma (HCC) are poorly characterized. This study aimed to evaluate the expression of PAR2 in HCC tissues and examine the prognostic value of PAR2 after resection in HCC.

Scarless Completion Thyroidectomy After Initial Transoral Approach for Differentiated Thyroid Cancer: How and When to Start?

Background: With growing literature, the feasibility of transoral endoscopic thyroidectomy vestibular approach (TOETVA) has been confirmed as a valid method for managing differentiated thyroid cancer. Completion thyroidectomy (CT) is recommended in patients who have been diagnosed with differentiated thyroid cancer after unilateral lobectomy by TOETVA. In this retrospective study, the authors addressed the critical questions of how and when to do the second operation of CT to avoid a neck scar.

The Perioperatively Altered Neutrophil-to-Lymphocyte Ratio Associates with Impaired DNA Damage Response in Liver Transplantation Recipients with Hepatocellular Carcinoma.
