The role of metals in autoimmune vasculitis: epidemiological and pathogenic study.

BACKGROUND: A possible relationship between Silica (Si) exposure and antineutrophil cytoplasm antibodies (ANCA)-associated vasculitis has been reported. Furthermore, tuberculosis (TBC) has been frequently described in patients with silicosis, and TBC infection shares with ANCA-associated vasculitis the formation of granulomas. Therefore, an intriguing network including Silica, Vasculitis, TBC and ANCA might be hypothesized. The aim of this work was to further investigate these correlations using both epidemiological and pathogenic approaches. METHODS: Study I--epidemiological study. A case-co

Health effects of endocrine-disrupting chemicals on wildlife, with special reference to the European situation.

Many wildlife species may be exposed to biologically active concentrations of endocrine-disrupting chemicals. There is strong evidence obtained from laboratory studies showing the potential of several environmental chemicals to cause endocrine disruption at environmentally realistic exposure levels. In wildlife populations, associations have been reported between reproductive and developmental effects and endocrine-disrupting chemicals. In the aquatic environment, effects have been observed in mammals, birds, reptiles, fish, and mollusks from Europe, North America, and other areas. The observe

Intervention and application of drawing therapy in cancer patients: a scoping review.

BACKGROUND: Cancer itself and its treatment process cause a range of physical and psychological discomforts to patients. Drawing therapy, as a form of complementary alternative medicine, has been proven to be effective in alleviating the physical and psychological discomforts of cancer patients, such as chemotherapy-associated nausea and vomiting, and negative emotions such as anxiety and depression. OBJECTIVE: This scoping review aims to organize and describe the literature on drawing therapy in cancer patients, including implementers, intervention methods, and effects. It strives to provide

[Brainstem auditory evoked responses in horses with hearing loss and during general anesthesia].

The brainstem auditory evoked response (BAER) is a diagnostic approach to examine the hearing system of horses objectively. The aim of this BAER examination was the diagnosis of conductive or sensorineural hearing loss or deafness in horses with external otitis, head trauma, headshaking, tinnitus or skittish horses with eye disease. Brainstem dysfunction is induced by intracranial hypotension. BAER was used in horses with colic surgery which had a low arterial blood pressure during general anesthesia. The endoscopic finding of the guttural pouch was the ipsilateral mild to severe hypertrophy o

Effect of expression of estrus and treatment with GnRH on pregnancies per AI in beef cattle synchronized with an estradiol/progesterone-based protocol.

Three experiments evaluated the effects of expression of estrus and gonadotropin releasing hormone (GnRH) treatment on pregnancies per AI (P/AI) in beef cattle that were treated with an estradiol/progesterone (P4)-based protocol for fixed-time artificial insemination (FTAI). In Experiment 1, 20 non-lactating beef cows were treated with 2 mg estradiol benzoate (EB) and an intravaginal device containing 0.5 g of P4. Seven days later, P4 devices were removed and all cows received prostaglandin F2 alpha (PGF2α) and 0.5 mg estradiol cypionate (ECP). Estrus was detected using tail paint and cows tha

The crystal structure of titanium dioxide nanoparticles influences immune activity in vitro and in vivo.

BACKGROUND: The use of engineered nanoparticles (NP) is widespread and still increasing. There is a great need to assess their safety. Newly engineered NP enter the market in a large variety; therefore safety evaluation should preferably be in a high-throughput fashion. In vitro screening is suitable for this purpose. TiO 2 NP exist in a large variety (crystal structure, coating and size), but information on their relative toxicities is scarce. TiO 2 NP may be inhaled by workers in e.g. paint production and application. In mice, inhalation of TiO 2 NP increases allergic reactions. Dendritic ce

Induction of reproductive cell death and chromosome aberrations in radioresistant tumour cells by carbon ions.

PURPOSE: To study the induction of reproductive cell death and chromosome aberrations in radioresistant tumour cells exposed to carbon ions in vitro. MATERIALS AND METHODS: X-ray-resistant colon carcinoma cells (WiDr) were used. Confluent G0/G1 cells were irradiated in vitro with graded doses of 100/200/400 MeV u(-1) carbon ions and carbon ions from the middle of a 1 cm extended Bragg peak, and 200 kV X-rays for comparison. Cells were harvested in their first post-irradiation division and aberrations were analysed either by the Giemsa/Hoechst 33258-staining technique or by the fluorescent in-

Toxicology and carcinogenesis studies of tetralin (CAS No. 119-64-2) in F344/N rats and B6C3F1 mice (inhalation studies).

Tetralin is used as an industrial solvent primarily for naphthalene, fats, resins, oils, and waxes; as a solvent and stabilizer for shoe polishes and floor waxes; as a solvent for pesticides, rubber, asphalt, and aromatic hydrocarbons (e.g., anthracene); as a dye solvent carrier in the textile industry; as a substitute for turpentine in lacquers, paints, and varnishes; in paint thinners and as a paint remover; in alkali-resistant lacquers for cleaning printing ink from rollers and type; as a constituent of motor fuels and lubricants; for the removal of naphthalene in gas distribution systems;

History of the diagnosis and treatment of critical limb ischemia and diabetic foot.

The history of the recognition and surgical treatment of lower limb ischemia dates back to the Middle Ages. The twin Saints Comas and Damian were ascribed to have saved a gangrenous limb in the 13th century and became patrons of future surgeons. The physicians that followed developed the theories of blood flow, anatomy of the arterial circulation, and recognition that occlusive disease was the cause of limb ischemia and gangrene. Innovative physicians developed the techniques of arterial surgery and bypass grafting to restore limb blood flow and allow healing of lesions. In the 1960s, the era

NTP Toxicology and Carcinogenesis Studies 2-Butoxyethanol (CAS NO. 111-76-2) in F344/N Rats and B6C3F1 Mice (Inhalation Studies).

2-Butoxyethanol is a member of a family of ethylene glycol monoalkyl ethers. It is used extensively as a solvent in surface coatings such as lacquers, enamels, varnishes, and latex paint; in paint thinners, paint stripping formulations, and inks; and in degreasers and industrial and household cleaners. 2-Butoxyethanol was nominated for study because of its widespread use in industrial and consumer applications, the potential for exposure to workers and the general population, and the absence of chronic toxicity data. Male and female F344/N rats and B6C3F1 mice were exposed to 2-butoxyethanol (

Reimagination in art and science: Seeing the familiar in a new light and creating new things that didn't exist before.

Many groundbreaking works in art and science owe their origins to the creative spark ignited by reimagination-the process whereby artists and scientists reinterpret and reframe past and existing knowledge, envisioning it in a new context that reveals new possibilities. Artistic and scientific innovation originating from reimagination brings to mind William Faulkner's famous line, "The past is never dead. It's not even past." [W. Faulkner, Requiem for a Nun (1)].

Dual color FISH on CBF primary acute myeloid leukemia.

In acute myeloid leukemia (AML), clonal chromosomal aberrations constitute markers of diagnostic value and the molecular characterization of numerous abnormalities has greatly improved the understanding of the biology of distinct subtypes of the disease. Two of the most common recurring chromosomal abnormalities in AML are t(8;21) and inversion of chromosome 16 or its variant which belong to core binding factor (CBF) AML group. We aimed to compare between cytogenetics and dual color Fluorescence In Situ Hybridization (FISH) regarding their sensitivity for detection of CBF AML associated transl

Molecular cytogenetic detection of chromosomal breakpoints in T-cell receptor gene loci.

Chromosomal aberrations with breakpoints in T-cell receptor (TCR) gene loci are recurrent in several T-cell malignancies. Although the importance of interphase cytogenetics has been extensively shown in B-cell lymphomas, hardly any molecular cytogenetic tools are available for recurrent changes in T-cell disorders. Thus, we have established fluorescence in situ hybridization (FISH)-based break-apart assays for the TCRA/D (14q11), TCRB (7q34) and TCRG (7p14) genes and the TCL cluster (14q32). The assays were validated in normal controls as well as in 43 T-cell malignancies with cytogenetically

Pediatric renal carcinoma associated with Xp11.2 translocations/TFE3 gene fusions and clinicopathologic associations.

Renal cell carcinomas (RCCs) are rare in children and studies of their subtypes and clinicopathologic associations are limited to small series. We identified 8 patients with RCC treated at our institution between 1981 and 2003, reviewed their clinicopathologic features, cytogenetics findings, and evaluated the status of TFE3 expression by immunohistochemistry and numerical chromosomal alterations by interphase fluorescent in situ hybridization on paraffin-embedded tissue. These 8 patients (5 female and 3 male) had diploidy, and 5 had morphologic features compatible with the recently described

Occurrence of pregnancy losses within the same lactation in grazing dairy cows.

The study aimed to describe pregnancy losses within the same lactation in a large commercial dairy herd in Argentina. A retrospective study was completed using 25,019 lactation records from 11,263 cows with at least 1 artificial insemination-declared pregnant (AIDP) by ultrasound at 28 to 42 d post AI. Each AIDP was identified according to the corresponding parity number, which was sequentially numbered and related to a pregnancy number within the same lactation. In each lactation, the uterine health events (UTE), retention of fetal membranes, puerperal metritis, and clinical endometritis, as

A Clinical Study of Anterior Abdominal Wall Hernias and Its Management: A Medical College Experience.

Materials and methods This prospective observational research was conducted between 2022 and 2024 at a tertiary care health center, involving 100 participants with an anterior abdominal wall hernia diagnosis aged over 14 years. The study excluded patients under 14 years with bleeding diathesis, inherited coagulopathies, inguinal or femoral hernias, or recurrent ventral hernias. Participants underwent detailed clinical examinations a

[Sleep in a performance artist: Eight days and seven nights sitting inside a metal sculpture].

Sleep in extreme situations has been little studied. The artist Abraham Poincheval (AP) is known for his performances in confined spaces. For his show at the Perrotin Gallery in Paris, he was enclosed for 8days and 7nights in a metal sculpture of his body in a seated position, with his head facing a work by Hans Hartung at the end of a cone system placed in front of his eyes which occluded all other visual stimuli. The interior of the metal structure was not padded and there was no head support. His sleep and internal temperature were continuously recorded using polysomnography (Grael, Compume

Current concepts in dyspepsia: a world perspective.

The meaning and definition of dyspepsia continues to challenge clinical investigators and has led to the setting up of several international working teams. However, confusion continues to reign around this term. The effort to classify patients with dyspepsia into subgroups according to their most predominant symptoms has failed to provide clues to the underlying disease, or even to discriminate between functional and organic dyspepsia. With these limitations in mind, the question arises: is there any reason for putting further effort into developing a world-wide definition of dyspepsia when, i

Concluding remarks: Achievements, challenges, and trajectories for high-entropy alloy nanoparticles.

The field of high-entropy alloy nanoparticles (HEA-NPs) had to move and indeed has moved beyond the early enthusiasm of simply "mixing five or more elements and hoping the configurational entropy will do some magic" in terms of chemical and physical properties. What the 2025 Faraday Discussion made clear is that, at the nanoscale, entropy is often a minor player. Phase stability, structure, and functional properties are instead dominated by kinetics, surface reconstruction, defects, segregation, decomposition, and - more often than we like to admit - (unnoticed) interstitial contamination (C,

Real-world assessment of a deep learning neural network algorithm for prostate cancer detection in MRI using true de novo data.

BACKGROUND: Deep-learning neural network algorithms for detecting prostate cancer in MRI have proliferated in the literature. However, out of 30+ studies published since the PROSTATEx challenge, no studies tested the performance of their algorithm against using true external image data sets (studies came from an outside institution that did not supply any training data to the algorithm) while validating against MR-US fusion biopsy or whole-mount prostatectomy. Using true external data sets paints a much clearer picture of real-world clinical performance of an algorithm. PURPOSE: This work wil
