Pheochromocytoma and paragangliomas (PPGLs) crises can be triggered by various factors, including norepinephrine reuptake inhibitors used to treat attention deficit hyperactivity disorder (ADHD), which worsen symptoms in patients with PPGLs. Therefore, attention should be paid to the potential for serious adverse reactions in patients with PPGLs taking ADHD medications. A 21-year-old man presented to the emergency department with acute onset of severe respiratory and circulatory failure after initiating atomoxetine treatment.

However, there is a knowledge gap regarding the optimal epinephrine dosing interval. This study aimed to examine the association between epinephrine dosing intervals and outcomes after out-of-hospital cardiac arrest (OHCA).

Methods: This study involved 13 consecutive patients who had received SVF cell therapy at our clinic before November 2015 and completed the 6-month post-treatment follow-up period. For each treatment, approximately 200 mL or more of subcutaneous adipose tissue was harvested using tumescent liposuction technique and manual aspiration of tissue from the lower abdomen using a suction cannula under local anesthesia in the operating room.
Background And Objective: Previous studies have suggested that human immunodeficiency virus (HIV) infection and/or the airway colonization of Pneumocystis jirovecii (Pcj) impact on the progression of airway obstruction, such as chronic obstructive pulmonary disease (COPD). This study was aimed to evaluate the relationship between HIV infection, airway colonization of Pcj and airway obstruction in Japanese male patients.
Methods: Case-control study of 49 HIV-positive and 257 HIV-negative men were enrolled in this study.

To elucidate the pathogenesis of HTLV-1-associated bronchopulmonary disorders, we analyzed the relationship between expression of p40(tax), a regulatory component of HTLV-1 that stimulates various host genes, and synthesis of pro-inflammatory cytokines and chemokines by cells in BAL fluid (BALF) obtained from HTLV-1-infected patients.
Design: Reverse transcription-polymerase chain reaction was used to compare the expression of p40(tax) and pro-inflammatory cytokines and chemokines messenger RNA (mRNA) in BALF of 10 HTLV-1 carriers and 7 healthy subjects.
Functional recovery of the immune system is critical for long-term survival in hematopoietic stem cell transplant recipients. In this study, two donor-recipient allogeneic transplant settings (haploidentical and fully mismatched) are used to investigate the functional activity of donor-derived B and T cells in animals grafted with purified c-kit(+), Thy 1.1(lo), Lin(-/lo), and Sca-1(+) hematopoietic stem cells (KTLS HSC).

Stromal epithelial and monocytic cells are infected by MV in thymus implants, and virulent strains induce massive thymocyte apoptosis, although thymocytes are not infected. To determine whether passage of an avirulent vaccine strain in human tissue increases virulence, we studied a virus isolated from thymic tissue 90 days after infection with the vaccine strain Moraten (pMor-1) and a virus isolated from an immunodeficient child with progressive vaccine-induced disease (Hu2).

We report here that HIV-1 infection of the SCID-hu Thy/Liv mouse leads to the induction of MHC class I (MHCI) expression on CD4+CD8+ (DP) thymocytes, which normally express low levels of MHCI. Induction of MHCI on DP thymocytes in HIV-1-infected Thy/Liv organs precedes their depletion and correlates with the pathogenic activity of the HIV-1 isolates.

Activation of unknown host intracellular events overcomes such inhibitory steps and is concomitant with HIV-1 replication. We show that the transcription factor NFATc was sufficient as a cellular factor to induce a highly permissive state for HIV-1 replication in primary CD4+ T cells.

When mutants were constructed by inserting stop codons into ORF47 and ORF66, the recombinants ROka47S and ROka66S, as well as intact ROka replicated in tissue culture. In contrast, inoculation of human thymus/liver or skin implants in SCID-hu mice showed that ORF47 protein was required for viral growth in human T cells and skin.

We have previously demonstrated that virulence phenotypes in human infections are faithfully reproduced by infection of human thymus/liver (thy/liv) implants engrafted into SCID mice, where the virus grows primarily in stromal cells but induces thymocyte apoptosis (P.

A successful hematopoietic stem/progenitor cell (HSPC)-based gene therapy strategy for HIV-1 disease must protect Mo/Mphi as well as T cells from HIV-1-related pathology. In this report, we demonstrate that RevM10-transduced HSPCs isolated from cytokine-mobilized peripheral blood give rise to Mo/Mphi suppressing replication of Mphi-tropic HIV-1 isolates.

Retroviral vectors expressing the antisense RNAs as part of the Moloney murine leukemia virus LTR promoter-directed retroviral transcript were constructed. The CD4+ T-cell line CEM-SS was transduced with retroviral constructs, and Northern blot analyses showed high steady-state antisense RNA expression levels.

Infection of human skin implants was used to investigate the basis for the clinical attenuation of the varicella-zoster virus (VZV) strain, V-Oka, from which the newly licensed vaccine is made. The pathogenicity of V-Oka was compared with that of its parent, P-Oka, another low-passage clinical isolate, strain Schenke (VZV-S), and VZV-Ellen, a standard laboratory strain.
