The Youngest Infant to Be Diagnosed with Autosomal Dominant Hypocalcemia Type 2 Harboring a Novel Variant of A Case Study and Literature Review.

Autosomal dominant hypocalcemia (ADH) is characterized by hypocalcemia and inappropriately low PTH concentrations. ADH type 2 (ADH2) is caused by a heterozygous gain-of-function mutation in that encodes the subunit of G11, the principal G protein that transduces calcium-sensing receptor signaling in the parathyroid. Clinical features related to hypocalcemia in ADH2 range from asymptomatic to tetany and seizures.

The Effect of Additional Private Health Insurance on Mortality in the Context of Universal Public Health Insurance.

(1) Background: Korea operates its national health insurance (NHI) system as a form of public health insurance, and is commonly regarded as having achieved universal health coverage (UHC). However, many Korean households register for additional private health insurance (PHI) programs. Typically, registration rates for PHI are higher for individuals with a higher socioeconomic status (SES).

The Effect of Labor and Relationship Exclusions on Older Korean Men with Depression.

To manage depression of older men, it is necessary to identify factors that influence depression and improve them. This study used the Korean Aging Longitude Research to understand the effects of labor exclusion and relationship exclusion on depression in Korean male seniors aged 65 and older. According to research on the effect of labor exclusion and relationship exclusion on depression, depression in the case where labor was excluded was 1.

The effect of xylometazoline spray for expansion of nasal cavity.

Background: During nasotracheal intubation it is important to have proper pretreatment for nasal mucosa constriction and nasal cavity expanding. Nasal packing of epinephrine gauze is widely used as well as xylometazoline. The aim of this study was to compare and evaluate the efficacy of prophylactic intranasal spray of xylometazoline against epinephrine gauze packing in expanding the nasal cavity.

AtGSNOR1 function is required for multiple developmental programs in Arabidopsis.

Nitric oxide (NO) has been proposed to regulate a diverse array of activities during plant growth, development and immune function. S-nitrosylation, the addition of an NO moiety to a reactive cysteine thiol, to form an S-nitrosothiol (SNO), is emerging as a prototypic redox-based post-translational modification. An ARABIDOPSIS THALIANA S-NITROSOGLUTATHIONE (GSNO) REDUCTASE (AtGSNOR1) is thought to be the major regulator of total cellular SNO levels in this plant species.

S-nitrosylation of NADPH oxidase regulates cell death in plant immunity.

Changes in redox status are a conspicuous feature of immune responses in a variety of eukaryotes, but the associated signalling mechanisms are not well understood. In plants, attempted microbial infection triggers the rapid synthesis of nitric oxide and a parallel accumulation of reactive oxygen intermediates, the latter generated by NADPH oxidases related to those responsible for the pathogen-activated respiratory burst in phagocytes. Both nitric oxide and reactive oxygen intermediates have been implicated in controlling the hypersensitive response, a programmed execution of plant cells at sites of attempted infection.

Cultured cambial meristematic cells as a source of plant natural products.

A plethora of important, chemically diverse natural products are derived from plants. In principle, plant cell culture offers an attractive option for producing many of these compounds. However, it is often not commercially viable because of difficulties associated with culturing dedifferentiated plant cells (DDCs) on an industrial scale.

HD-ZIP III activity is modulated by competitive inhibitors via a feedback loop in Arabidopsis shoot apical meristem development.

Shoot apical meristem (SAM) development is coordinately regulated by two interdependent signaling events: one maintaining stem cell identity and the other governing the initiation of lateral organs from the flanks of the SAM. The signaling networks involved in this process are interconnected and are regulated by multiple molecular mechanisms. Class III homeodomain-leucine zipper (HD-ZIP III) proteins are the most extensively studied transcription factors involved in this regulation.

Nitric oxide function and signalling in plant disease resistance.

Nitric oxide (NO) is one of only a handful of gaseous signalling molecules. Its discovery as the endothelium-derived relaxing factor (EDRF) by Ignarro revolutionized how NO and cognate reactive nitrogen intermediates, which were previously considered to be toxic molecules, are viewed. NO is now emerging as a key signalling molecule in plants, where it orchestrates a plethora of cellular activities associated with growth, development, and environmental interactions.

S-nitrosylation: an emerging redox-based post-translational modification in plants.

S-nitrosylation, the covalent attachment of a nitric oxide moiety to a cysteine thiol, is now established as a key post-translational modification in animals. This process has been shown to regulate the function of a wide variety of regulatory, structural, and metabolic proteins. The emerging evidence now suggests that S-nitrosylation may also have a central function in plant biology.

A central role for S-nitrosothiols in plant disease resistance.

Animal S-nitrosoglutathione reductase (GSNOR) governs the extent of cellular S-nitrosylation, a key redox-based posttranslational modification. Mutations in AtGSNOR1, an Arabidopsis thaliana GSNOR, modulate the extent of cellular S-nitrosothiol (SNO) formation in this model plant species. Loss of AtGSNOR1 function increased SNO levels, disabling plant defense responses conferred by distinct resistance (R) gene subclasses.
