Self-aggregation of 13,13-disubstituted bacteriochlorophyll-d analog.

Zinc methyl 13,13-disubstituted 3-hydroxymethyl-pyropheophorbides-a were prepared as models of bacteriochlorophyll-d, which self-aggregated in the main light-harvesting antenna (chlorosome) of photosynthetic green bacteria. The synthetic zinc 3-hydroxy-13-oxo-chlorins possessing methyl and methoxycarbonyl groups at the 13-position could not self-aggregate in an aqueous Triton X-100 solution. However, another model compound bearing an ethane-1,2-diyl group at the 13-position did self-aggregate under the same conditions to give red-shifted and broadened Qy and Soret absorption bands.

Substrate specificities in the chlorophyll catabolism of aquatic protists determined with in vivo phagocytotic assays.

Chlorophylls (Chls) are ubiquitous photosynthetic pigments with inherent potential to generate cytotoxic reactive oxygen species. Therefore, all phototrophs and any phagotrophs that attempt to digest phototrophic cells have presumably developed mechanisms to mitigate this phototoxicity. In aquatic environments, the Chls produced by the dominant producers, microalgae, are catabolized into nonphototoxic pigments, cyclopheophorbide enols (CPEs), either by microalga-feeding protists or autonomously, particularly by those carrying secondary chloroplasts during the dismantling of their chloroplasts.

Na-V-ATPase inhibitor curbs VRE growth and unveils Na pathway structure.

Vancomycin-resistant Enterococcus faecium (VRE) is a major cause of nosocomial infections, particularly endocarditis and sepsis. With the diminishing effectiveness of antibiotics against VRE, new antimicrobial agents are urgently needed. Our previous research demonstrated the crucial role of Na-transporting V-ATPase in Enterococcus hirae for growth under alkaline conditions.

False-Negative Motor-Evoked Potential Due to Contrast-Induced Encephalopathy During Coil Embolization for Intracranial Aneurysm: A Case Report.

Contrast-induced encephalopathy (CIE) is a rare neurological complication that can occur following the use of contrast media during angiographic procedures. It can lead to neurological deficits, such as motor weakness. Transcranial motor-evoked potential (TcMEP) monitoring is commonly used to detect pyramidal tract disorders during embolization for intracranial aneurysms.

Gamma-glutamyl cyclotransferase, a molecule identified from the invasive front of follicular thyroid carcinoma, is useful for differential diagnosis of follicular thyroid tumors.

We aimed to establish a useful molecular marker for differentiating between follicular thyroid carcinoma (FTC) and follicular adenoma (FA). RNA was extracted from the invasive front and paired tumor center tissues from three FTC cases using laser microdissection for cDNA microarray analysis, revealing high expression of gamma-glutamyl cyclotransferase (GGCT) in the invasive front. Subsequently, immunohistochemical (IHC) staining of GGCT was performed with formalin-fixed paraffin-embedded (FFPE) sections of FTC (n = 32), FA (n = 64), and follicular tumor of uncertain malignant potential (FT-UMP, n = 5).

Hypertension is associated with the reduction in epidermal small fibres independently of sural nerve inflammation in type 2 diabetic subjects.

Diabetic polyneuropathy (DPN) is a multifactorial disease associated not only with hyperglycaemia but also with circulatory disturbances such as hypertension. A close interaction between the immune system and hypertension is known. It remains unclear whether the inflammatory response is associated with hypertension in the pathology of human DPN.

Dual effects of targeting neuropilin-1 in lenvatinib-resistant hepatocellular carcinoma: inhibition of tumor growth and angiogenesis.

In the era of immunotherapy, lenvatinib (LEN) still holds an important position in the sequential treatment of advanced hepatocellular carcinoma (HCC). However, the sustained therapeutic effect of LEN is not sufficient, and there is a need to address the development of resistance. Neuropilin-1 (NRP1) is known to act as a coreceptor for epidermal growth factor receptor (EGFR), Met, and vascular endothelial growth factor receptor 2 (VEGFR2), which have been reported to be involved in LEN resistance.

Assessment of Tie2-Rejuvenated Nucleus Pulposus Cell Transplants from Young and Old Patient Sources Demonstrates That Age Still Matters.

Cell transplantation is being actively explored as a regenerative therapy for discogenic back pain. This study explored the regenerative potential of Tie2 nucleus pulposus progenitor cells (NPPCs) from intervertebral disc (IVD) tissues derived from young (<25 years of age) and old (>60 years of age) patient donors. We employed an optimized culture method to maintain Tie2 expression in NP cells from both donor categories.

Sonic hedgehog expression in steatohepatitic hepatocellular carcinoma and its clinicopathological significance.

Hedgehog (Hh) signaling pathway dysregulation is involved in the pathogenesis of metabolic dysfunction-associated steatohepatitis, and the sonic Hh (SHh) protein, a pivotal molecule in the Hh pathway, is expressed in ballooned hepatocytes. The present study aimed to investigate the clinicopathological significance of SHh expression in steatohepatitic hepatocellular carcinoma (SH-HCC). Reverse transcription-quantitative polymerase chain reaction and immunohistochemistry were performed to examine gene and SHh protein expression in SH-HCC.

Moderate cryptoxanthin intake correlates with maintenance of a proper PINT index in a general Japanese population.

Introduction: Small fibre neuropathy (SFN) is an early manifestation of diabetic polyneuropathy. Although oxidative stress, inflammation and change of intestinal bacterial population are assumed to be their pathogenesis, the effects of dietary nutrition have not been evaluated. The relationship between dietary nutrition intake and pain sensation was evaluated in the Japanese population.

A Comparison of the Effects of Alcohol Abstinence and Drinking Habit on the Survival of Patients with Alcohol-related Cirrhosis: A Retrospective Observational Study.

Objective Abstaining from alcohol improves the outcome of alcohol-related cirrhosis. This study evaluated the effect of alcohol abstinence on the outcomes of patients with alcohol-related cirrhosis recruited from a core hospital in Boso Peninsula, Japan. Methods This single-center retrospective study recruited 116 patients with alcohol-related cirrhosis who were admitted to our department between April 2014 and October 2022.

Extra-Annulated Chlorophyll Derivatives by Scholl Reaction.

The ferric chloride assisted Scholl reaction of methyl (3,5-dimethoxyphenyl)carbonyl-pyropheophorbide- produced an extra-annulated, didehydrogenated chlorophyll derivative with a six-membered ring fused at the pyrrole A-ring. The steric interaction of the substituents on the additional tetralone and B-rings induced molecular helicity. The helically cyclized stereoisomers were separated by recrystallization, and their (/)-stereochemistry was confirmed by circular dichroism spectra.

Cytokine release syndrome following durvalumab and tremelimumab in advanced hepatocellular carcinoma: A case report with cytokine and damage-associated molecular pattern analysis.

Cytokine release syndrome (CRS) is a systemic inflammatory syndrome that causes fatal circulatory failure due to hypercytokinemia, and subsequent immune cell hyperactivation caused by therapeutic agents, pathogens, cancers, and autoimmune diseases. In recent years, CRS has emerged as a rare, but significant, immune-related adverse event linked to immune checkpoint inhibitor therapy. Furthermore, several previous studies suggested that damage-associated molecular patterns (DAMPs) could be involved in malignancy-related CRS.

Enhancement of transcription efficiency by TAR-Tat system increases the functional expression of human olfactory receptors.

Humans have approximately 400 different olfactory receptors (hORs) and recognize odorants through the repertoire of hOR responses. Although the cell surface expression of hORs is critical to evaluate their response, hORs are poorly expressed on the surface of heterologous cells. To address this problem, previous studies have focused on hOR transportation to the membrane.

Non-invasive hERG channel screening based on electrical impedance tomography and extracellular voltage activation (EIT-EVA).

hERG channel screening has been achieved based on electrical impedance tomography and extracellular voltage activation (EIT-EVA) to improve the non-invasive aspect of drug discovery. EIT-EVA screens hERG channels by considering the change in extracellular ion concentration which modifies the extracellular resistance in cell suspension. The rate of ion passing in cell suspension is calculated from the extracellular resistance , which is obtained from the EIT measurement at a frequency of 500 kHz.
