Objective: Data were extracted from preexisting published studies and evaluated retrospectively to compare lactate and base deficit values at baseline and posthemorrhage with changes in corresponding hemoglobin (Hb) and Hct measurements to assess any association of such changes with severity of hemorrhage over time. To understand the goal, the objective of this study was to demonstrate statistical changes in laboratory values as described above.

Methods: Previous prospectively designed experiments on 120 mixed-breed dogs were conducted.

Oral delivery of peptide therapeutics is limited by degradation by gut proteases like chymotrypsin. Existing databases of peptidases are limited in size and do not enable systematic analyses of protease substrate preferences, especially for non-natural amino acids. Thus, stability optimization of hit compounds is time and resource intensive.

Inherently limited by poor bioavailability, antiviral agent tenofovir (TFV) is administered to people living with HIV in prodrug form. However, current prodrugs are prematurely metabolized, compromising access to HIV-infected cells and inducing toxicity. Inspired by lipid conjugate TFV exalidex (TXL), we recently disclosed TXL analogs with potent activity and robust hepatic stability in vitro, as well as attractive oral PK profiles in vivo.

Background: Hemoglobin disorders such as thalassemia major have created an economic burden on the health care system. Iron chelation therapy (ICT) is the most expensive cost component in patients with thalassemia. ICT was administered to reduce the toxic effects of iron overload.

Background: Organ donation shortage and in particular organ procurement is an international concern as the gap between the number of donors and recipients is steadily growing. Organ procurement is a chain of steps with donor identification and referral (ID&R) as the very first link in this chain. Failure of this step hinders the progress in the organ transplantation program.

Murine typhus (MT), an infection caused by the gram-negative bacteria Rickettsia typhi (R. typhi), is a significant cause of acute febrile illness (AFI) in Southeast Asia but is rarely reported in Indonesia. The current study aimed to describe the clinical characteristics of MT cases in Bandung, West Java.

Peptides have historically been underutilized for covalent inhibitor discovery, despite their unique abilities to interact with protein surfaces and interfaces. This is in part due to a lack of methods for screening and identifying covalent peptide ligands. Here, we report a method to identify covalent cyclic peptide inhibitors in mRNA display.

Objective: This study aims to adapt the English-language Hospital Anxiety and Depression Scale (HADS) to the Indonesian language and evaluate the validity and reliability of the adapted version (ie, HADS-Indonesia).

Design: A cross-sectional study was conducted between June and November 2018. First, a translation and back-translation process was conducted by a committee consisting of the researchers, a psychiatrist, a methodology consultant and two translators.

Background & Objectives: Although the World Health Organization recommends same day or rapid (< seven days) antiretroviral therapy (ART) initiation, delays in ART initiation remain common due to waiting for laboratory test results. This study employed a simplified clinical algorithm the HATI [HIV Awal (Early) Test & Treat Indonesia]-SAI (Simple ART Initiation) aimed to increase the proportion of ART uptake and decrease the time to ART initiation that can be used in various care settings.

Methods: This study compared the percentage of ART uptake and retention, viral load (VL) suppression and time to ART initiation between the observation and intervention phases among newly diagnosed HIV patients from key populations.

Background: Thalidomide (THD) and its analogues were recently reported as a promising treatment for different types of solid tumors due to their antiangiogenic effect.

Methods: In this work, we synthesized a novel THD analogue (TA), and its chemistry was confirmed with different techniques such as IR, mass spectroscopy, elemental analysis as well as H and C NMR. To increase solubility and anticancer efficacy, a new oil in water (O/W) nanoemulsion (NE) was used in the formulation of the analogue.

mRNA display is revolutionizing peptide drug discovery through its ability to quickly identify potent peptide binders of therapeutic protein targets. Methods to expand the chemical diversity of display libraries are continually needed to increase the likelihood of identifying clinically relevant peptide ligands. Orthogonal aminoacyl-tRNA synthetases (ORSs) have proven utility in cellular genetic code expansion, but are relatively underexplored for translation (IVT) and mRNA display.

Background: Chronic malnutrition in children is a severe global health concern. In Yogyakarta, the number of children who are too short for their age has dropped dramatically over the past few decades.

Objective: To perform an analysis of trends, policies, and programs; and an assessment of government, community, household, and individual drivers of the stunting reduction in Yogyakarta, Indonesia.

Merck & Co. recently reported one of the first mRNA display-derived clinical candidates in a bioavailable inhibitor of proprotein convertase subtilisin/kexin type 9 (PCSK9). Herein, we discuss the chemical and pharmacological challenges surmounted in bringing this compound to trials and the current outlook for mRNA display-based therapeutic development.

Background: Restless leg syndrome (RLS) is a common neurological condition that manifests as creeping, nonpainful urges to move lower extremities and is relieved with movements of the legs. RLS is associated with comorbidities such as gastric surgery, diabetes mellitus, uremia, and iron deficiency anemia, and it is misdiagnosed in many cases. Drugs like levodopa, ropinirole, pramipexole, cabergoline, and pergolide that target the dopaminergic system have been traditionally used to treat symptoms of RLS.

Stunting has been a public health problem in several developing countries including Indonesia. One of the strategies to reduce stunting was family assistance. This study was aimed to estimate the effect of family assistance by using an integrative nutrition package through home visits on the growth and development of stunted children.

Stunting is primarily a public health concern in Low- and Middle-Income Countries (LMIC). The involvement of Integrated Health Service Post (Indonesian: Posyandu) cadres is among the strategies to combat stunting in Indonesia. This study aimed to determine the effect of a short course on cadres' knowledge.

Tenofovir (TFV) is the cornerstone nucleotide reverse transcriptase inhibitor (NtRTI) in many combination antiretroviral therapies prescribed to patients living with HIV/AIDS. Due to poor cell permeability and oral bioavailability, TFV is administered as one of two FDA-approved prodrugs, both of which metabolize prematurely in the liver and/or plasma. This premature prodrug processing depletes significant fractions of each oral dose and causes toxicity in kidney, bone, and liver with chronic administration.

The power of ribosomes has increasingly been harnessed for the synthesis and selection of molecular libraries. Technologies, such as phage display, yeast display, and mRNA display, effectively couple genotype to phenotype for the molecular evolution of high affinity epitopes for many therapeutic targets. Genetic code expansion is central to the success of these technologies, allowing researchers to surpass the intrinsic capabilities of the ribosome and access new, genetically encoded materials for these selections.
