γδ T cell-mediated activation of cDC1 orchestrates CD4+ Th1 cell priming in malaria
Full text linkNagasaki University (長崎大学)博士(医学)γδ T cells facilitate the CD4+ T helper 1 (Th1) cell response against Plasmodium infection by activating conventional dendritic cells (cDCs), although the underlying mechanism remains elusive. Our study revealed that γδ T cells promote the complete maturation and production of interleukin-12 and CXCR3-ligands specifically in type 1 cDCs (cDC1), with minimal impact on cDC2 and monocyte derived DCs (Mo-DCs). During the initial infection phase, γδ T cell activation and temporal accumulation in the splenic white pulp, alongside cDC1, occur via CCR7-signaling. Furthermore, cDC1/γδ T cell interactions in the white pulp are amplified through CXCR3 signaling in γδ T cells, optimizing Th1 cell priming by cDC1. We also demonstrated how transitional Th1 cells arise in the white pulp before establishing their presence in the red pulp as fully differentiated Th1 cells. Additionally, we elucidate the reciprocal activation between γδ T cells and cDC1s. These findings suggest that Th1 cell priming is orchestrated by this reciprocal activation in the splenic white pulp during the early phase of blood-stage Plasmodium infection.長崎大学学位論文 学位記番号:博(医歯薬)甲第1695号 学位授与年月日:令和7年3月19日Author: Yarob Ibraheem, Ganchimeg Bayarsaikhan, Maria Lourdes Macalinao, Kazumi Kimura, Katsuyuki Yui, Taiki Aoshi and Shin-Ichi InoueCitation: Frontiers in Immunology, 15, art. no. 1426316; 2024Nagasaki University (長崎大学), 博士(医学) (2025-03-19)doctoral thesi
Postmortem injection of calcium chloride Improves camel meat tenderness
No full textTwenty-four hours postmortem longissimus muscles of camel
carcasses were injected to 0 (control), 200 and 300 mM food grade
CaCl2 at 10% (wt/wt), vacuum- packaged and stored at 2ºC for 6 days.
Drip loss, cooking loss, sarcomere length, and shear force were
determined. At 6 days post-treatment, samples with CaCl2 had higher
(P <0.05) drip loss compared to non-injected ones, however; cooking
loss was not affected (P >0.05). Muscle sarcomere length was not
significantly affected (P >0.05) but shear force values for treated
samples were lower (P <0.05) than those of controls with ratios varied
from 23.4% and 32.4% lower for the 200 and 300 mM injections,
respectively, and therefore; calcium chloride injection is an effective
method for improving camel meat tenderness.Corresponding Author:

Ozone Holes: Where and Size, Bad and Good
No full textStratospheric ozone is considered a natural sunscreen that protects life from harmful ultraviolet (UV) rays from the Sun for hundreds of millions of years. Ozone holes consist of exceptionally depleted ozone in stratosphere over the Antarctic, North Pole, and Tibetan mountains with measured concentration less than 220 Dobson Units. Studies showed the incidence of skin cancer increases by 2% for each percent of ozone reduction. Chlorofluorocarbons (CFCs) and Hydrochlorofluorocarbons (HCFCs) used in HVAC and refrigeration devices are said to be the perpetrators that release chlorine when leaked to ground air, diffuse to the stratosphere, dissociate to active ions, and catalyze and destroy ozone molecules (2 O3  3 O2). Ozone depletion and ozone holes in recent decades have caught huge global attentions and worries. Banning ozone-depleting refrigerants such as CFCs and HCFCs has been enforced through international agreements for the past two decades.Why do ozone holes appear in places where little population and effectively no HVAC and refrigeration are used? Why aren't there any holes over Los Angeles, New Mexico city, Shanghai, Paris, Hong Kong, where millions of ACs and refrigerators are used? Why is the distribution of UV radiation on Earth ground is found high near the equator, where ozone layer is not thin or dilute? Why do the ozone holes shrink or expand over different seasons of the year, if they are solely man-made? Are increasing incidences of skin cancer and eyes problem are primarily caused by depletion of stratospheric ozone? People believe ozone holes are bad; can they lead to any good outcome to humanity? This paper will collect and compare scientific data and take a different approach in seeking the truths of ozone depletion and holes. The authors will strive to address some of the questions mentioned above and explain the phenomena about ozone hole, its size, its location, and any bad and good impacts and the role of depleting chemicals, CFCs.This Research Day material is made accessible to the global community via the web

Investigation of zoonotic disease pathogens (Aeromonas hydrophila, Pseudomonas fluorescens, Streptococcus iniae) seen in carp farms in the Northern Iraq-Erbil region by molecular methods
No full textThe aim of this study was to determine the zoonotic bacteria in carp farms in the Northern Iraq-Erbil region. Carp is the main fish species cultured in Erbil region. The most common zoonotic bacteria generally seen in carp farms are Aeromonas hydrophila, Pseudomonas fluorescens and Streptococcus iniae. Samples were collected from 25 carp farms in the Northern Iraq-Erbil region. Six carp samples were collected from each carp farm. Head kidney and intestine tissue samples were collected from each carp sample. Then head kidney and intestine tissue samples were pooled separately from each carp farm. Total bacterial DNA had been extracted from the 25 pooled head kidney and 25 intestinal tissue samples. The pathogen Primers were originally designed from 16S RNA gene region. Zoonotic bacteria were scanned in all tissue samples with absent/present analysis by RT-PCR. Furthermore, the capillary gel electrophoresis bands were used for confirmation of amplicon size which was planned during primer designing stage. As a result, thirteen carp farms were positive in the respect to Aeromonas hydrophila, eight carp farms were positive from head kidney and six carp farms were positive from the intestine, only one carp farm was positive from both head kidney and the intestine tissue samples. In the respect to Streptococcus iniae, four carp farms were positive from head kidney and two carp farms were positive from the intestine. Only one carp farm was positive in the respect to Pseudomonas fluorescens from the intestine. Totally, 9 of 25 carp farms were cleared (negative) the zoonotic bacteria. In conclusion, the zoonotic bacteria were high (64 %) in carp farms in the Northern Iraq-Erbil region
