Crypto-coding technique based on polar code and secret key generated from wireless channel characteristics for wireless communication systems.

The crypto-coding technique is essential for modern digital wireless communications systems, allowing data encryption and channel coding to be performed in only one step without requiring additional hardware. This work proposes a crypto-coding technique combining polar codes with a secret key, which is derived from wireless channel characteristics, to boost the security and reliability characteristics of the systems. The secret key is divided into two parts, one is assigned to the frozen bits, and the other is XORed with the information bits.

An updated overview on long-acting therapeutics for the prevention and treatment of human immunodeficiency virus (HIV) from a perspective of pharmaceutics.

Conventional drug formulations release active pharmaceutical ingredients (APIs) immediately after administration, while long-acting (LA) drug products are designed for prolonged therapeutic effects, thereby reducing administration frequency and improving patient compliance. The development of LA therapeutics for chronic disease treatment has significantly helped patients adhere to their regimens, reducing the need for daily doses and easing the burden on healthcare systems. Advances in treatment have transformed Human Immunodeficiency Virus (HIV) into a manageable chronic disease, and efforts are underway to eliminate HIV in the future.

Ionic liquids and their potential use in development and improvement of drug delivery systems: evidence of their tendency to promote drug accumulation in the brain.

Ionic liquids (ILs) are considered salt in liquid state, which is composed of organic cations and anions with low melting points (<100 °C). ILs have become a major scientific area with an extensive range of applications including chemistry, electrochemistry, and pharmaceutics. ILs have received great research interest in the pharmaceutical field as solvents, anti-solvents, co-solvents, and reagents in synthesis and formulation.

The trial started with a period where all recruiting centers provided routine antenatal care without study-related intervention.

Oral Drug Delivery via Intestinal Lymphatic Transport Utilizing Lipid-Based Lyotropic Liquid Crystals.

Lyotropic liquid crystals (LLCs) are liquids that have crystalline structures. LLCs as drug delivery systems that can deliver hydrophobic, hydrophilic, and amphiphilic agents. Due to their unique phases and structures, LLCs can protect both small molecules and biologics from the gastrointestinal tract's harsh environment, thus making LLCs attractive as carriers for oral drug delivery.

DISC1 and reelin interact to alter cognition, inhibition, and neurogenesis in a novel mouse model of schizophrenia.

The etiology of schizophrenia (SCZ) is multifactorial, and depending on a host of genetic and environmental factors. Two putative SCZ susceptibility genes, Disrupted-in-Schizophrenia-1 (DISC1) and reelin (RELN), interact at a molecular level, suggesting that combined disruption of both may lead to an intensified SCZ phenotype. To examine this gene-gene interaction, we produced a double mutant mouse line.

Unbalanced Translocation in a Phenotypically Normal Male Patient Detected by Karyotyping and Array-comparative Genomic Hybridization.

Background: nbalanced translocations can cause developmental delay, intellectual disability, growth problems, dysmorphic features, and congenital anomalies Unbalanced chromosome rearrangements that are cytogenetically visible account for ~3% of all recognized chromosome abnormalities. A lot of unbalanced translocations have been reported.

Objective: Here, we present an individual who has an unbalanced translocation caused by deletion of the terminal region of chromosome 5p encompassing 170 kb coupled with a 11.

variants of dominant monogenic disorders in Vietnam detected by a noninvasive prenatal test: a case series.

Noninvasive prenatal tests for monogenic diseases (NIPT-SGG) have recently been reported as helpful in early-stage antenatal screening. Our study describes the clinical and genetic features of cases identified by NIPT-SGG. In a cohort pregnancy with abnormal sonograms, affected cases were confirmed by invasive diagnostic tests concurrently, with NIPT-SGG targeting 25 common dominant single-gene diseases.

Preparation and characterization of lysozyme loaded liposomal dry powder inhalation using non-ionic surfactants.

Delivering protein drugs through dry powder inhalation (DPI) remains a significant challenge. Liposomes offer a promising solution, providing protection for proteins from external environment and controlled release capabilities. Furthermore, the use of non-ionic surfactants plays a crucial role in protecting the activity of proteins because of how the surfactants positioning themselves at the liquid-gas interface during the spray-drying process.

Developing and validating noninvasive prenatal testing for autosomal dominant monogenic diseases in Vietnam.

Over 60% of single-gene diseases in newborns are autosomal dominant variants. Noninvasive prenatal testing for monogenic conditions (NIPT-SGG) is cost-effective and timesaving, but not widely applied. This study introduces and validates NIPT-SGG in detecting 25 monogenic conditions.

Use of artificial intelligence in forecasting glaucoma progression.

Artificial intelligence (AI) has been widely used in ophthalmology for disease detection and monitoring progression. For glaucoma research, AI has been used to understand progression patterns and forecast disease trajectory based on analysis of clinical and imaging data. Techniques such as machine learning, natural language processing, and deep learning have been employed for this purpose.

Synthesis of Celecoxib-Eutectic Mixture Particles via Supercritical CO Process and Celecoxib Immediate Release Tablet Formulation by Quality by Design Approach.

Significant improvements in the wettability and dissolution rate of celecoxib (CEL), a poorly soluble selective cyclooxygenase-2 (COX-2) inhibitor, have been shown by Huyn et al., 2019 by combining the binary pharmaceutical compositions including CEL and one of the two co-formers, adipic acid (ADI) and saccharin (SAC), into eutectic mixtures (EM). In this study, we developed a therapeutic eutectic system for CEL which is a promising approach for oral delivery to enhance bioavailability.

A novel thermosensitive poloxamer-hyaluronic acid- kappa-carrageenan-based hydrogel anti-adhesive agent loaded with 5-fluorouracil: A preclinical study in Sprague-Dawley rats.

Although the first-choice treatment for colorectal cancer is cytoreductive surgery combined with chemotherapy, post-surgical peritoneal adhesion and extant malignancy can cause fatal complications. Studies examining hydrogel-based postoperative anti-adhesion treatments are still limited. In this study, several formulations of 5-fluorouracil (5-FU) loaded into hyaluronic acid (HA) and kappa-carrageenan (kCGN)-poloxamer 407 (P407)-based cross-linked hydrogels were prepared and evaluated in vitro and in vivo for their efficacy in preventing adhesion.

Assessment of 6 STR loci for prenatal diagnosis of Duchenne Muscular Dystrophy.

Objective: Duchenne Muscular Dystrophy is an X-linked recessive disorder characterized by progressive muscular degeneration, patients often develop cardiac failure in the later stage and death occurs before 20 years of age. For a disease with poor postnatal prognosis such as Duchenne Muscular Dystrophy (DMD), providing the carrier mother with the option of prenatal diagnosis in a subsequent pregnancy is accepted practice in many places where termination of pregnancy is allowed. Though methods of direct sequencing such as Sanger's sequencing has been widely used, Next-Generation Sequencing is been increasingly replacing most of its application.

Mosaicism in carrier of Duchenne muscular dystrophy mutation - Implication for prenatal diagnosis.

Objective: Duchenne muscular dystrophy (DMD) is a severe disorder caused by mutation in the X-linked dystrophin gene, therefor carrier testing is required for all female family members. However, there are cases mutation analysis cannot detect any mutation due to a phenomenon called mosaicism. The case report describes a case of mosaicism in a DMD carrier and discusses the approach in diagnosis and counseling of familial disorder.
