Ruptured large hepatic cyst with elevated serum and ascites CA19-9 level.

Tumor markers such as carbohydrate antigen 19-9 (CA19-9) are generally useful in ruling out malignancy of hepatic cysts. The patient was a 72-year-old man who had a ruptured liver cyst in the right liver, which had been noted since he was 67 years old at another hospital. The initial laboratory tests demonstrated elevated CA19-9 (193 784.

Influence of radiation exposure to delayed fetal growth in wild Japanese monkeys after the Fukushima accident.

Wild Japanese monkeys () were exposed to radiation after the Fukushima Daiichi nuclear accident in 2011. To clarify the biological effects of radiation exposure on their fetal growth, pregnant monkeys and their fetuses were analyzed. These animals were collected between 2008 and 2020 (before and after the accident in 2011) living in Fukushima City, approximately 70 km from the nuclear power plant.

Time dependence of Cs contamination in wild Japanese monkeys after the Fukushima Daiichi nuclear accident.

Over the 10 years immediately after the Fukushima Daiichi nuclear accident, we measured the changes in the muscle Cs concentration (Bq/kg) of wild Japanese monkeys living in Fukushima City, which is located approximately 70 km from the Fukushima Daiichi Nuclear Power Plant. The muscleCsconcentration, which was observed at a maximum of 13,500 Bq/kg immediately after the accident, had decreased to several hundred Bq/kg 10 years later. The muscle Cs concentration was significantly related to the soil contamination levels (10,000-30,000, 30,000-60,000, 60,000-100,000, and 100,000-300,000 Bq/m), sex, age class (immature, mature), body weight (> 5000 g, 5000-10,000 g, < 10,000 g), and seasons (the cold period from December to April, the warm period from May to November).

Clinical Impact of Dual Time Point F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography Fusion Imaging in Pancreatic Cancer.

We examined the value of preoperative dual time point (DTP) 18F-fluorodeoxyglucose positron emission tomography/computed tomography fusion imaging (FDG PET/CT) as a predictor of early recurrence or the outcomes in patients with pancreatic cancer. Standardized uptake values (SUVs) in DTP FDG PET/CT were performed as preoperative staging. SUVmax1 and SUVmax2 were obtained in 60 min and 120 min, respectively.

Effects of flat-flexible shoes on lower limb joint kinetics and kinematics in gait.

Flat-flexible shoes with unique characteristics, such as low pitch and flexibility, can increase the efficiency of ankle energy and running performance. If flat-flexible shoes have the same effect during walking, they could be used for gait training. This study aimed to investigate the effects of flat-flexible shoes on the kinematics and kinetics of the lower limb.

Encephalitozoon cuniculi takes advantage of efferocytosis to evade the immune response.

Microsporidia are recognized as opportunistic pathogens in individuals with immunodeficiencies, especially related to T cells. Although the activity of CD8+ T lymphocytes is essential to eliminate these pathogens, earlier studies have shown significant participation of macrophages at the beginning of the infection. Macrophages and other innate immunity cells play a critical role in activating the acquired immunity.

Concentrations of Cs radiocaesium in the organs and tissues of low-dose-exposed wild Japanese monkeys.

Objectives: Following the massive earthquake that struck eastern Japan on March 11, 2011, a large amount of radioactive material was released into the environment from the damaged reactor of the Fukushima Daiichi Nuclear Power Plant (FDNPP). After the FDNPP accident, radiocaesium was first detected in muscle samples from wild Japanese monkeys exposed to radioactive materials, and haematologic effects, changes in head size, and delayed body weight gain were also reported, but little is known about the distribution of Cs in the organs and tissues of wild Japanese monkeys.

Results: We detected the Cs in various organ and tissue samples of 10 wild Japanese monkeys inhabiting the forested areas of Fukushima City that were captured between July and August 2012.

B-1 cell-mediated modulation of M1 macrophage profile ameliorates microbicidal functions and disrupt the evasion mechanisms of Encephalitozoon cuniculi.

Here, we have investigated the possible effect of B-1 cells on the activity of peritoneal macrophages in E. cuniculi infection. In the presence of B-1 cells, peritoneal macrophages had an M1 profile with showed increased phagocytic capacity and index, associated with the intense microbicidal activity and a higher percentage of apoptotic death.

CytoLyt fixation significantly inhibits MIB1 immunoreactivity whereas alternative Ki-67 clone 30-9 is not susceptible to the inhibition: Critical diagnostic implications.

Background: The Ki-67 proliferation marker has multiple diagnostic and prognostic applications. Although several clones to the Ki-67 antigen are commercially available, the MIB1 clone is widely recommended in the surgical pathology literature for neuroendocrine tumors. In our cytopathology practice, we have encountered unexpectedly low MIB1 immunoreactivity in CytoLyt-fixed cell blocks (CBs).

Dichotomous response of Malassezia-infected macrophages to Malassezia pachydermatis and Malassezia furfur.

Malassezia pachydermatis and Malassezia furfur are lipophilic yeasts of the cutaneous microbiome, although these organisms are occasionally responsible for serious invasive infections in neonates. Since phagocytosis is an important mechanism mediating the adaptive immune response, here we evaluated the phagocytosis capacity and production of nitric oxide and cytokine by macrophages after challenged with M. furfur CBS-1878 and M.

Immunohistochemical analysis of estrogen receptor in breast cancer with ESR1 mutations detected by hybrid capture-based next-generation sequencing.

Estrogen receptor-α (ER-α), encoded by ESR1, is detected by immunohistochemistry in approximately 70% of invasive breast cancers and serves as a strong predictive biomarker. ESR1-activating mutations in the ligand-binding domain have been reported in up to 35-40% of ER-positive metastatic breast cancers and are associated with endocrine therapy resistance and disease progression. At present, it is unclear whether ESR1 mutations alter the immunohistochemical detection of ER performed in routine clinical practice.

Small head size and delayed body weight growth in wild Japanese monkey fetuses after the Fukushima Daiichi nuclear disaster.

To evaluate the biological effect of the Fukushima Daiichi nuclear disaster, relative differences in the growth of wild Japanese monkeys (Macaca fuscata) were measured before and after the disaster of 2011 in Fukushima City, which is approximately 70 km from the nuclear power plant, by performing external measurements on fetuses collected from 2008 to 2016. Comparing the relative growth of 31 fetuses conceived prior to the disaster and 31 fetuses conceived after the disaster in terms of body weight and head size (product of the occipital frontal diameter and biparietal diameter) to crown-rump length ratio revealed that body weight growth rate and proportional head size were significantly lower in fetuses conceived after the disaster. No significant difference was observed in nutritional indicators for the fetuses' mothers.

Cytologic assessment of estrogen receptor, progesterone receptor, and HER2 status in metastatic breast carcinoma.

Background: Discordance in the receptor status between primary breast carcinomas (PBC) and corresponding metastasis is well documented. Interrogation of the receptor status of metastatic breast carcinoma (MBC) in cytology material is common practice; however, its utility has not been thoroughly validated. We studied patients with MBC, and evaluated the concordance rates of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) between PBC surgical specimens and corresponding MBC cell blocks (CBs).

High dilutions of antimony modulate cytokines production and macrophage - Leishmania (L.) amazonensis interaction in vitro.

Background: In previous results mice treated with high dilutions of antimony presented reduction of monocyte migration to the site of infection with increase in B lymphocytes population in the local lymph node.

Aims: To know the mechanisms involved, a series of in vitro studies was done, using co-cultures of macrophages (RAW 264.7) and Leishmania (L.

Culture and propagation of microsporidia of veterinary interest.

Microsporidia are obligate intracellular mitochondria-lacking pathogens that rely on host cells to grow and multiply. Microsporidia, currently classified as fungi, are ubiquitous in nature and are found worldwide. They infect a large number of mammals and are recognized as opportunistic infection agents in HIV-AIDS patients.

B-1 cells promote immunosurveillance against murine melanoma in host absence of CCR5: new perspective in autologous vaccination therapy.

Autologous vaccination with tumor-primed dendritic cells increases immune response against tumor, which seems to be improved in host absence of CCR5. Because B-1 lymphocytes modulate the activity of different immune cells, we decided to study their influence in the resistance against murine B16F10 melanoma in a CCR5 deprived environment. Adoptive transfer of peritoneal B-1 CCR5(+/+) lymphocytes to CCR5(-/-) animals inhibited the establishment of lung metastasis and melanoma cell growth, in comparison to saline-treated CCR5(-/-) mice.

[A case of advanced rectal cancer that showed complete response to the addition of XELOX+bevacizumab therapy to preoperative chemoradiotherapy with S-1/CPT-11].

A 51-year-old man presented with a chief complaint of constipation. Rectal cancer was detected up to 13 cm proximal to the anal verge. The cancer was a fully circumferential type II tumor that was accompanied by prostate invasion and lymph node metastasis.

Breast carcinoma with tubulopapillary features: a variant of papillary carcinoma with a stronger correlation with predictors of adverse prognosis.

Papillary carcinoma of the breast consists of 3 morphologically distinct established subtypes: encapsulated papillary carcinoma, solid papillary carcinoma, and invasive papillary carcinoma. Papillary carcinoma is one of the special types of breast cancer and, as such, carries a more favorable prognosis. We sought to identify primary breast tumors with tubulopapillary morphology and correlate this finding with predictors of adverse prognosis.

Concentration of radiocesium in the wild Japanese monkey (Macaca fuscata) over the first 15 months after the Fukushima Daiichi nuclear disaster.

Following the massive earthquake that struck eastern Japan on March 11, 2011, a nuclear reactor core meltdown occurred at the Fukushima Daiichi Nuclear Power Plant, operated by Tokyo Electric Power Company, and was followed by the release of large amounts of radioactive materials. The objective of this study was to measure the concentration of radiocesium (134)Cs and (137)Cs in the muscle of Japanese monkeys (Macaca fuscata) inhabiting the forest area of Fukushima City and to determine the change in concentration over time as well as the relationship with the level of soil contamination. Cesium concentrations in the muscle of monkeys captured at locations with 100,000-300,000 Bq/m(2) were 6,000-25,000 Bq/kg in April 2011 and decreased over 3 months to around 1,000 Bq/kg.
