Instant Gaussian Splatting Generation for High-Quality and Real-Time Facial Asset Rendering.

Traditional and AI-driven modeling techniques enable high-fidelity 3D asset generation from scans, videos, or text prompts. However, editing and rendering these assets often involves a trade-off between quality and speed. In this paper, we propose GauFace, a novel Gaussian Splatting representation, tailored for efficient rendering of facial mesh with textures.

Shifting paradigms in primary aldosteronism: reconsideration of screening strategy via integrating pathophysiological insights.

Several decades have passed since the description of the first patient with primary aldosteronism (PA). PA was initially classified in two main forms: aldosterone-producing adenoma (APA) and idiopathic hyperaldosteronism (IHA). However, the pathogenesis of PA has now been shown to be far more complex.

ACTH stimulation and oral salt loading tests detect biochemical outcome early after primary aldosteronism surgery.

Background: In primary aldosteronism (PA), the biochemical outcomes of the Primary Aldosteronism Surgical Outcome study are used to assess aldosterone hypersecretion 6-12 months after surgery. However, few studies have investigated whether the outcomes can be predicted in the early postoperative period. In this retrospective study, we evaluated whether the adrenocorticotropin stimulation test (AST) and oral salt loading test (OST) performed immediately after surgery could predict biochemical outcomes 1 year after surgery.

A novel method for measurements of sleep/wake states, feeding and drinking behaviors using the tracking technique of 3D positions in freely moving mice.

We have previously developed a 3D video tracking system which enables us to analyze long-term quantitative analysis of gene expression in freely moving mice. In the present study, we improved 3D video tracking and developed a system that analyzes more detailed behavioral data. We succeeded in simultaneously analyzing sleep-wake, feeding, and drinking behavior rhythms in the same individual using our tracking system.

Adrenal venous sampling criteria for chemiluminescent enzyme immunoassay as a preferable alternative to radioimmunoassay in primary aldosteronism.

Plasma aldosterone concentration (PAC) was routinely measured using radioimmunoassay (RIA); however, the RIA kit was discontinued in March 2021 in Japan. This study examined PAC conversion in adrenal venous sampling (AVS) and AVS criteria when measured using chemiluminescent enzyme immunoassay (CLEIA). PAC of 415 adrenal venous blood samples from AVS (including segmental AVS) of 63 patients with primary aldosteronism was measured using RIA (Spac-S aldosterone kit; Fujirebio Inc.

Identifying primary aldosteronism patients who require adrenal venous sampling: a multi-center study.

Adrenal venous sampling (AVS) is crucial for subtyping primary aldosteronism (PA) to explore the possibility of curing hypertension. Because AVS availability is limited, efforts have been made to develop strategies to bypass it. However, it has so far proven unsuccessful in applying clinical practice, partly due to heterogeneity and missing values of the cohorts.

Lethal Arrhythmia Induced by Severe Hypokalemia with Primary Aldosteronism: A Case Report and Literature Review.

A 26-year-old woman experienced sudden loss of consciousness with respiratory arrest while engaged in a heated conversation shortly after consuming a carbohydrate-rich meal; she was resuscitated immediately. Severe hypokalemia became evident and was deemed to have caused lethal arrhythmia. She was diagnosed with a left aldosterone-producing adenoma and achieved remission following partial adrenalectomy.

Differences between left adrenal vein sampling sites revealed with segmental sampling in primary aldosteronism.

Objectives: To clarify the differences between two left sampling sites (left adrenal central vein [LCV] and common trunk [CMT], conjunction with LCV and inferior phrenic vein) and their impact on adrenal venous sampling (AVS) in primary aldosteronism by analyzing the results of segmental AVS (sAVS).

Methods: We retrospectively analyzed a final cohort of 432 patients who underwent cosyntropin-stimulated sAVS from 2017 to 2020. Hormone levels in the LCV and the CMT were compared.

High aldosterone levels in the renal capsular vein from the left aldosterone-producing adenoma on adrenal venous sampling.

Summary: A 42-year-old female patient was referred to our hospital with hypertension and hypokalemia and was diagnosed with primary aldosteronism. Dynamic contrast-enhanced computed tomography images revealed a 13-mm nodule on the lateral segment of the left adrenal gland and a fine venous connection between the nodule and the prominent renal capsular vein running nearby. The venograms in the left lateral tributary with a microcatheter confirmed alternative drainage to the left renal capsular vein during adrenal venous sampling, and the left renal capsular vein sampling was added.

Feasibility of single-port laparoscopic partial adrenalectomy with selective adrenal venous sampling and high-resolution ultrasound for unilateral aldosterone-producing adenomas.

Background: The surgical and endocrinological outcomes of single-port laparoscopic partial adrenalectomy for patients with aldosterone-producing adenomas are unknown. Precise diagnosis of intra-adrenal aldosterone activity and a precise surgical procedure may improve outcomes. In this study, we aimed to determine the surgical and endocrinological outcomes of single-port laparoscopic partial adrenalectomy with preoperative segmental selective adrenal venous sampling and intraoperative high-resolution laparoscopic ultrasound in patients with unilateral aldosterone-producing adenomas.

Structural insight into an anti-BRIL Fab as a G-protein-coupled receptor crystallization chaperone.

Structure determination of G-protein-coupled receptors (GPCRs) is key for the successful development of efficient drugs targeting GPCRs. BRIL is a thermostabilized apocytochrome b (with M7W/H102I/R106L mutations) from Escherichia coli and is often used as a GPCR fusion protein for expression and crystallization. SRP2070Fab, an anti-BRIL antibody Fab fragment, has been reported to facilitate and enhance the crystallization of BRIL-fused GPCRs as a crystallization chaperone.

Node-by-node diagnosis for multiple ipsilateral nodules by segmental adrenal venous sampling in primary aldosteronism.

Objectives: In patients with primary aldosteronism (PA), multiple adrenocortical nodules may be present on the surgical side. The aim of this study was to clarify the pathological diagnosis and the node-by-node diagnostic capability of segmental adrenal venous sampling (sAVS).

Design: Retrospective study.

Association Between Aldosterone and Hypertension Among Patients With Overt and Subclinical Hypercortisolism.

Introduction: Hypertension is one of the most common clinical features of patients with overt and subclinical hypercortisolism. Although previous studies have shown the coexistence of autonomous cortisol and aldosterone secretion, it is unclear whether aldosterone plays a role in hypertension among patients with hypercortisolism. Therefore, we examined the associations of plasma aldosterone concentrations (PACs) with hypertension among patients with overt and subclinical hypercortisolism.

Mixed corticomedullary tumor of the adrenal gland.

Mixed corticomedullary tumor (MCMT) of the adrenal gland is an extremely rare tumor characterized by an admixture of steroidogenic cells and chromaffin cells in a single tumor mass simultaneously producing adrenocortical hormones and catecholamines; it is associated with ectopic adrenocorticotropic hormone (ACTH) in some cases. We reviewed and summarized clinicopathological data of 28 MCMTs, including four metastatic tumors in 26 previous reports. These reports included 21 females and 7 males, and the average tumor sizes were 4.

Aldosterone-Producing Adenomas of Increased Size Are Associated With Higher Steroidogenic Activity.

Context: There are inconsistent results and insufficient evidence as to whether an association exists between the size and aldosterone-producing ability of aldosterone-producing adenomas.

Objective: We further investigated this possible association retrospectively.

Methods: A total of 142 cases of primary aldosteronism diagnosed as unilateral by adrenal venous sampling at 2 referral centers between 2009 and 2019 were included.

A Case of I-Metaiodobenzylguanidine Scintigraphy-Negative Pheochromocytoma with a Tumor-Developing Mutation in the Gene.

Pheochromocytoma (PCC) is rare catecholamine-producing endocrine tumor that metastasizes in approximately 10% of cases. As a functional imaging of PCC, 123I-metaiodobenzylguanidine (MIBG) scintigraphy was established, and some cases of PCC exhibit negative accumulation on MIBG scintigraphy, indicating a high risk of metastasis. Additionally, germline genetic variants of PCC are evident in approximately 30% of cases, although the genotype-phenotype correlation in PCC, especially the association between genetic mutations and MIBG scintigraphy, remains unclear.

Comparison of Echocardiographic Changes Between Surgery and Medication Treatment in Patients With Primary Aldosteronism.

Background Primary aldosteronism can cause cardiac dysfunction, including left ventricular hypertrophy, left ventricular diastolic dysfunction, and left atrial enlargement. A few studies have compared the cardioprotective effects between surgery and medication for primary aldosteronism, although most have not adjusted for baseline disease status. In this study, we investigated the difference in cardiovascular outcomes between surgery and medication treatment for primary aldosteronism after adjusting for baseline clinical characteristics, including aldosterone level and pretreatment echocardiographic information.

Phenotypic Variability in a Family with Carney Complex Accompanied by a Novel Mutation Involving PRKAR1A.

Carney complex is a rare, autosomal dominant disease accompanied by multiple endocrine neoplastic syndromes. Mutations in the PRKAR1A gene have recently been reported as a cause of Carney complex, but genotype-phenotype correlations vary widely. A 15-year-old Japanese man (Case 1) with short stature visited our hospital with suspected Cushing's syndrome.

Characteristics of aldosterone-producing adenomas in patients without plasma renin activity suppression.

Primary aldosteronism (PA) usually accompanies suppressed plasma renin activity (PRA) through a negative feedback mechanism. While some cases of PA with unsuppressed PRA were reported, there have been no studies about the characteristics of PA with unsuppressed PRA; thus, these characteristics were examined herein. Nine patients with unsuppressed PRA and 86 patients with suppressed PRA were examined.

Carney Complex Complicated with Primary Pigmented Nodular Adrenocortical Disease without Cushing's Syndrome Recurrence for Five Years after Unilateral Adrenalectomy.

We herein report a case of Carney complex (CNC) complicated with primary pigmented nodular adrenocortical disease (PPNAD) after unilateral adrenalectomy. A 44-year-old woman was admitted to our hospital for PPNAD surgery. She had previously undergone surgery for cardiac myxoma and had a PRKAR1A mutation with no family history of CNC.

Radiological characteristics and diagnostic impact of duplicated right adrenal veins on adrenal venous sampling in primary aldosteronism.

Purpose: We aimed to analyze the prevalence and radiological characteristics of duplicated right adrenal veins (DRAVs) and evaluate the diagnostic impact of adrenal venous sampling (AVS) in primary aldosteronism.

Methods: DRAVs were retrospectively identified among patients who underwent segmental AVS between April 2017 and March 2020. DRAVs were defined as main or accessory according to the drainage area.

Immunohistochemical Expression of Choline Acetyltransferase and Catecholamine-Synthesizing Enzymes in Head-and-Neck and Thoracoabdominal Paragangliomas and Pheochromocytomas.

Paragangliomas (PGLs) are neural-crest-derived, non-epithelial neuroendocrine tumors distributed along the parasympathetic and sympathetic nerves. Head-and-neck PGLs (HNPGLs) have been recognized as nonchromaffin, nonfunctional, parasympathetic tumors. By contrast, thoracoabdominal paragangliomas and pheochromocytomas (PPGLs) are chromaffin, functional, sympathetic tumors.
