In cases of agglutination and complement fixation, cross titrations were made. 1. In the sera derived from rabbits immunized with various spirochetes agglutinins were demonstrated in varying qua

Association study between intestinal microbiota dysbiosis in inflammatory bowel disease and the global disease burden growth trend.

BACKGROUND: Inflammatory bowel disease (IBD), including ulcerative colitis and Crohn's disease, is a group of chronic intestinal inflammatory diseases. Its incidence and prevalence have been on the rise globally, imposing a heavy burden on patients' health and social medical resources. Intestinal microbiota dysbiosis is believed to play a crucial role in the occurrence and development of IBD, but the association between them and the global disease burden growth trend remains unclear. METHODS: By searching the Global Burden of Disease (GBD) study database, we collected IBD disease burden data

Trichloroethylene: An Invisible Cause of Parkinson's Disease?

The etiologies of Parkinson's disease (PD) remain unclear. Some, such as certain genetic mutations and head trauma, are widely known or easily identified. However, these causes or risk factors do not account for the majority of cases. Other, less visible factors must be at play. Among these is a widely used industrial solvent and common environmental contaminant little recognized for its likely role in PD: trichloroethylene (TCE). TCE is a simple, six-atom molecule that can decaffeinate coffee, degrease metal parts, and dry clean clothes. The colorless chemical was first linked to parkinsonism

Aptamers: Potential Diagnostic and Therapeutic Agents for Blood Diseases.

Aptamers are RNA/DNA oligonucleotide molecules that specifically bind to a targeted complementary molecule. As potential recognition elements with promising diagnostic and therapeutic applications, aptamers, such as monoclonal antibodies, could provide many treatment and diagnostic options for blood diseases. Aptamers present several superior features over antibodies, including a simple in vitro selection and production, ease of modification and conjugation, high stability, and low immunogenicity. Emerging as promising alternatives to antibodies, aptamers could overcome the present limitations

Non-cryopreserved Autologous Peripheral Blood Stem Cell Transplantation for Lymphoma in a Resource-Limited Setting: Feasibility, Engraftment Kinetics, and Early Outcomes From Kashmir, India.

Background  Autologous stem cell transplantation (ASCT) is a standard consolidation strategy for selected patients with relapsed or high-risk lymphoma, but access remains limited in many low- and middle-income regions because of the cost and infrastructure required for stem cell cryopreservation. Non-cryopreserved ASCT using fresh peripheral blood stem cells stored at 4°C may provide a practical alternative. Methods  We retrospectively analyzed 11 consecutive patients with lymphoma who underwent non-cryopreserved ASCT at the Department of Medical Oncology, Sher-i-Kashmir Institute of Medical S

Recent advances in use of fresh frozen plasma, cryoprecipitate, immunoglobulins, and clotting factors for transfusion support in patients with hematologic disease.

Hematologic diseases include a broad range of acquired and congenital disorders, many of which affect plasma proteins that control hemostasis and immune responses. Therapeutic interventions for these disorders include transfusion of plasma, cryoprecipitate, immunoglobulins, or convalescent plasma-containing therapeutic antibodies from patients recovering from infectious diseases, as well as concentrated pro- or anticoagulant factors. This review will focus on recent advances in the uses of plasma and its derivatives for patients with acquired and congenital hematologic disorders.

Intravenous zoledronic acid for the treatment of osteoporosis: The evidence of its therapeutic effect.

INTRODUCTION: Osteoporosis is a disease characterized by low bone mineral density and poor bone quality resulting in reduced bone strength and increased risk of fracture. Oral bisphosphonates, first-line therapy for most patients with osteoporosis, are associated with suboptimal adherence to therapy due to factors that include a complex dosing regimen and gastrointestinal intolerance in some patients. Intravenous bisphosphonates address these limitations through infrequent injectable dosing that assures 100% bioavailability. Intravenous zoledronic acid is the newest bisphosphonate to be approv

Brazilian Nutritional Consensus in Hematopoietic Stem Cell Transplantation: Adults.

The nutritional status of patients submitted to hematopoietic stem cell transplant is considered an independent risk factor, which may influence on quality of life and tolerance to the proposed treatment. The impairment of nutritional status during hematopoietic stem cell transplant occurs mainly due to the adverse effects resulting from conditioning to which the patient is subjected. Therefore, adequate nutritional evaluation and follow-up during hematopoietic stem cell transplant are essential. To emphasize the importance of nutritional status and body composition during treatment, as well a
