Evaluation of the Combinatory Anticancer Effect of Chemotherapeutic Compounds and Prodigiosin against HCT-116, LoVo, and A549 Cell lines.

Despite their wide usage in reducing tumors and improving patients' survival, chemotherapeutic drugs or natural compounds are facing the development of cancer resistance. Many experimental data and clinical trials have shown that combinatorial treatment could be an efficient solution for some resistance problems. In this study, we aimed to evaluate the synergistic effects of combining prodigiosin (PG), a natural compound with known anticancer properties, with the commonly used chemotherapy drugs 5-fluorouracil (5-FU), oxaliplatin, and paclitaxel.

Autism and Intellectual Disability-Associated Mutation Alters Human Cortical Interneuron Differentiation, Maturation, and Physiology.

MYT1L is a neuronal transcription factor highly expressed in the developing and adult brain. While pathogenic mutation causes neurodevelopmental disorders, these have not been characterized in human models of neurodevelopment. Here, we defined the consequences of pathogenic mutation in human pluripotent stem cell-derived cortical interneurons.

Narrative cave art in Indonesia by 51,200 years ago.

Previous dating research indicated that the Indonesian island of Sulawesi is host to some of the oldest known rock art. That work was based on solution uranium-series (U-series) analysis of calcite deposits overlying rock art in the limestone caves of Maros-Pangkep, South Sulawesi. Here we use a novel application of this approach-laser-ablation U-series imaging-to re-date some of the earliest cave art in this karst area and to determine the age of stylistically similar motifs at other Maros-Pangkep sites.

Cationic-motif-modified exosomes for mRNA delivery to retinal photoreceptors.

Topical treatment of vitreoretinal diseases remains a challenge due to slow corneal uptake and systemic clearance. Exosomes are emerging nanocarriers for drug delivery due to biocompatibility and cellular targeting properties. To apply them for retinal targeting the topical route, exosomes must traverse various ocular barriers including the cornea, lens, vitreous humor (VH), and the retina itself.

A multimodality review of gynecologic devices in the pelvis.

There are a wide variety of gynecologic devices encountered on pelvic imaging which may not be the focus or primary reason for imaging. Such devices include pessaries, menstrual products, radiation therapy devices, tubal occlusion devices, and contraceptive devices, including intrauterine devices and intravaginal rings. This manuscript offers a comprehensive review of multimodality imaging appearances of gynecologic devices encountered on pelvic imaging and discusses device indications, positioning, and complications.

Toxicity evaluation of synthetic glucocorticoids against breast cancer cell lines MDA-MB-231, MCF-7 and human embryonic kidney HEK293.

In this study, we conducted a comprehensive assessment of the cytotoxicity of three glucocorticoids, namely Hydrocortisone, Dexamethasone, and Methylprednisolone, using three different human cell lines: MDA-MB-231, MCF-7 (both adenocarcinoma cell lines), and HEK293 (kidney epithelial cell line). At lower concentrations exceeding 50 µM, we did not observe any significant toxic effects of these glucocorticoids. However, when exposed to higher concentrations, Hydrocortisone exhibited dose-dependent cytotoxic effects on all three cell lines, with calculated IC50 values of 12 ± 0.

A Comprehensive Review of Bioactive Compounds from Lactic Acid Bacteria: Potential Functions as Functional Food in Dietetics and the Food Industry.

Lactic acid bacteria (LAB) are beneficial microbes known for their health-promoting properties. LAB are well known for their ability to produce substantial amounts of bioactive compounds during fermentation. Peptides, exopolysaccharides (EPS), bacteriocins, some amylase, protease, lipase enzymes, and lactic acid are the most important bioactive compounds generated by LAB activity during fermentation.

PKC-βII is downregulated in the premature ovarian failure SD rat model.

We investigated the role of protein kinase c (PKC) -α and -β during the ovarian follicular dynamics using estrous cycle, gonadotropin-induced ovulation, and antral follicle culture, 4-vinylcyclohexene diepoxide (VCD)-induced premature ovarian failure (POF) in the SD rat models. We found the higher activity of PKC during the proestrus stage along with expression of PKC-α during the estrus and metestrus stages of the estrous cycle while PKC-β expression was increased during the diestrus, proestrus, and estrus stages. In response to pregnant mare gonadotropin (PMSG)-induced follicular recruitment and ovulation, the phosphorylated (Thr-642) PKC-β was increased.

Charge-based drug delivery to cartilage: Hydrophobic and not electrostatic interactions are the dominant cause of competitive binding of cationic carriers in synovial fluid.

Charge-based drug delivery has proven to be effective for targeting negatively charged cartilage for the treatment of osteoarthritis. Cartilage is surrounded by synovial fluid (SF), which is comprised of negatively charged hyaluronic acid and hydrophobic proteins that can competitively bind cationic carriers and prevent their transport into cartilage. Here we investigate the relative contributions of charge and hydrophobic effects on the binding of cationic carriers within healthy and arthritic SF by comparing the transport of arginine-rich cartilage targeting cationic peptide carriers with hydrophilic (CPC +14N) or hydrophobic property (CPC +14A).

Cationic peptide carriers enable long-term delivery of insulin-like growth factor-1 to suppress osteoarthritis-induced matrix degradation.

Background: Insulin-like growth factor-1 (IGF-1) has the potential to be used for osteoarthritis (OA) treatment but has not been evaluated in clinics yet owing to toxicity concerns. It suffers from short intra-joint residence time and a lack of cartilage targeting following its intra-articular administration. Here, we synthesize an electrically charged cationic formulation of IGF-1 by using a short-length arginine-rich, hydrophilic cationic peptide carrier (CPC) with a net charge of +14, designed for rapid and high uptake and retention in both healthy and arthritic cartilage.

Chemical alternative for cell identification and cross-contamination detection.

Misidentification of human cell lines has previously led to confusing results during cell culture experiments. Although several enzymatic as well as molecular analysis approaches have been developed for cell-line authentication, these methods remain costly. In the present paper, we describe a simple chemical alternative based on known compound cell cytotoxicity.

Higher Parental Age and Lower Educational Level are Associated with Underweight among Preschool Children in Terengganu, Malaysia.

This cross-sectional study aimed to investigate the determinants of underweight among preschool children. A total of 218 preschool children were enrolled. Their sociodemographic data were collected using self-reported questionnaires whilst body weight and height were measured, recorded and the BMI for-age z-score was calculated using WHO AnthroPlus software.

Skeletal remains of a Pleistocene modern human (Homo sapiens) from Sulawesi.

Major gaps remain in our knowledge of the early history of Homo sapiens in Wallacea. By 70-60 thousand years ago (ka), modern humans appear to have entered this distinct biogeographical zone between continental Asia and Australia. Despite this, there are relatively few Late Pleistocene sites attributed to our species in Wallacea.

Genome of a middle Holocene hunter-gatherer from Wallacea.

Much remains unknown about the population history of early modern humans in southeast Asia, where the archaeological record is sparse and the tropical climate is inimical to the preservation of ancient human DNA. So far, only two low-coverage pre-Neolithic human genomes have been sequenced from this region. Both are from mainland Hòabìnhian hunter-gatherer sites: Pha Faen in Laos, dated to 7939-7751 calibrated years before present (yr cal BP; present taken as AD 1950), and Gua Cha in Malaysia (4.

A standardised classification scheme for the Mid-Holocene Toalean artefacts of South Sulawesi, Indonesia.

The archaeology of Sulawesi is important for developing an understanding of human dispersal and occupation of central Island Southeast Asia. Through over a century of archaeological work, multiple human populations in the southwestern region of Sulawesi have been identified, the most well-documented being that of the Mid- to Late Holocene 'Toalean' technological period. Archaeological models for this period describe a population with a strong cultural identity, subdivided into groups living on the coastal plains around Maros as well as dispersed upland forest dwellers, hunting endemic wildlife with bow-and-arrow technology.

The effects of climate change on the Pleistocene rock art of Sulawesi.

The equatorial tropics house some of the earliest rock art yet known, and it is weathering at an alarming rate. Here we present evidence for haloclasty (salt crystallisation) from Pleistocene-aged rock art panels at 11 sites in the Maros-Pangkep limestone karsts of southern Sulawesi. We show how quickly rock art panels have degraded in recent decades, contending that climate-catalysed salt efflorescence is responsible for increasing exfoliation of the limestone cave surfaces that house the ~ 45 to 20-thousand-year-old paintings.

Electroporation of Mouse Follicles, Oocytes and Embryos without Manipulating Zona Pellucida.

Electroporation is an effective technique of transfection, but its efficiency depends on the optimization of various parameters. In this study, a simplified and efficient method of gene manipulation was standardized through electroporation to introduce a recombinant green fluorescent protein (GFP) construct as well as RNA-inhibitors in intact mouse follicles, oocytes and early embryos, where various electroporation parameters like voltage, pulse number and pulse duration were standardized. Electroporated preantral follicles were cultured further in vitro to obtain mature oocytes and their viability was confirmed through the localization of a known oocyte maturation marker, ovastacin, which appeared to be similar to the in vivo-derived mature oocytes and thus proved the viability of the in vitro matured oocytes after electroporation.

Oldest cave art found in Sulawesi.

Indonesia harbors some of the oldest known surviving cave art. Previously, the earliest dated rock art from this region was a figurative painting of a Sulawesi warty pig (). This image from Leang Bulu' Sipong 4 in the limestone karsts of Maros-Pangkep, South Sulawesi, was created at least 43,900 years ago (43.

Anti- (MAP) therapy for Crohn's disease: an overview and update.

The role of subspecies (MAP) in the pathogenesis of Crohn's disease (CD) has been strongly debated for many years. MAP is the known aetiological agent of Johne's disease, a chronic enteritis affecting livestock. At present, due to the paucity of high-quality data, anti-MAP therapy (AMT) is not featured in international guidelines as a treatment for CD.

Validating earliest rice farming in the Indonesian Archipelago.

Preserved ancient botanical evidence in the form of rice phytoliths has confirmed that people farmed domesticated rice (Oryza sativa) in the interior of Sulawesi Island, Indonesia, by at least 3,500 years ago. This discovery helps to resolve a mystery about one of the region's major events in natural and cultural history, by documenting when rice farming spread into Indonesia, ultimately from a source in mainland China. At the Minanga Sipakko site in Sulawesi, preserved leaf and husk phytoliths of rice show the diagnostic morphology of domesticated varieties, and the discarded husks indicate on-site processing of the crops.

Portable art from Pleistocene Sulawesi.

The ability to produce recognizable depictions of objects from the natural world-known as figurative art-is unique to Homo sapiens and may be one of the cognitive traits that separates our species from extinct hominin relatives. Surviving examples of Pleistocene figurative art are generally confined to rock art or portable three-dimensional works (such as figurines) and images engraved into the surfaces of small mobile objects. These portable communicative technologies first appear in Europe some 40 thousand years ago (ka) with the arrival of H.

Earliest hunting scene in prehistoric art.

Humans seem to have an adaptive predisposition for inventing, telling and consuming stories. Prehistoric cave art provides the most direct insight that we have into the earliest storytelling, in the form of narrative compositions or 'scenes' that feature clear figurative depictions of sets of figures in spatial proximity to each other, and from which one can infer actions taking place among the figures. The Upper Palaeolithic cave art of Europe hosts the oldest previously known images of humans and animals interacting in recognizable scenes, and of therianthropes-abstract beings that combine qualities of both people and animals, and which arguably communicated narrative fiction of some kind (folklore, religious myths, spiritual beliefs and so on).

Effect of Sequence of Fruit Intake in a Meal on Satiety.

Little is known about the effects of manipulating sequence of fruit consumption during a meal in suppressing an individual's appetite. Therefore, we investigate the effects of the sequence of fruit intake on satiety and blood glucose in a group of 17 healthy, young male adults. This intervention study repeatedly measured the effects of fruit intake (120 g red apple) before and after a meal and control (no fruit).

Robust Detection for Chipless RFID Tags Based on Compact Printable Alphabets.

This work presents a novel technique for designing chipless radio frequency identification (RFID) tags which, unlike the traditional tags with complex geometries, are both compact and printable. The tags themselves are alphabets, which offers the advantage of efficient visual recognition of the transmitted data in real-time via radio frequency (RF) waves. In this study, the alphabets (e.
