A novel insight into transcriptional and epigenetic regulation underlying sex expression and flower development in melon (Cucumis melo L.).

Melon (Cucumis melo L.) is an important cucurbit and has been considered as a model plant for studying sex determination. The four most common sexual morphotypes in melon are monoecious (A-G-M), gynoecious (--ggM-), andromonoecious (A-G-mm), and hermaphrodite (--ggmm).

Effect of ampicillin and chloroquine on humoral immune response elicited by bovine albumin encapsulated in liposomes.

Immune suppression resulting from chemoprophylaxis and potential drug interaction were investigated in experimental animals pre-medicated with ampicillin and chloroquine followed by immunization with bovine serum albumin bearing liposomes prepared by the reverse phase evaporation method. The prepared liposomes were evaluated for particle size, entrapment efficiency and in vitro release. Humoral immune response was measured in terms of systemic IgG antibody titre by the ELISA method.

Pyrexia following total knee replacement.

This study aims to determine the incidence and factors associated with pyrexia following total knee replacement (TKR). We performed a retrospective analysis of the temperature charts and histories of patients who underwent 170 TKRs. There was a statistically significant increase in mean temperature from pre-operation to post-operation, and this increase remained significant through to 5 days post surgery (p<0.

The heterogeneous spectrum of the long QT syndrome.

The long QT syndrome affects predominantly younger people who demonstrate structurally normal hearts. The underlying defect in the long QT syndrome seems to be genetic mutations in the cardiac ionic channels responsible for generating action potentials. Genetic linkage mapping has identified six genes (designated LQT1-6) associated with the Romano-Ward syndrome; two of these genes (LQT1, LQT5) are associated with the Jervell and Lange-Nielsen syndrome.

Effect of intra-articular steroids on deep infections following total knee arthroplasty.

Intra-articular steroids have been commonly used for the treatment of arthritis. The aim of our study was to discover any relation between deep infections following total knee arthroplasty and intra-articular steroid use before the arthroplasty. We undertook a retrospective matched cohort study.

Granulocytic sarcoma presenting as bilateral adrenal masses.

Granulocytic sarcoma (GS) is a collection of immature myeloid cells contained outside the bone marrow often seen in association with acute myeloid leukemia or as a sign of leukemic transformation in myeloproliferative disorders. Rarely, GS is an isolated finding unaccompanied by another hematological disorder. GS can occur at a variety of sites, most commonly involving the bone, soft tissue, lymph nodes, or skin.

Audible implantable cardioverter defibrillator alarms detect intermittent conductor discontinuity.

The lead conductor integrity of implantable cardioverter defibrillator devices is inferred from impedance measurements; however, intermittent discontinuity can be difficult to detect or confirm. Newer devices can perform daily lead impedance self-testing, and some even have audible alarms that promptly warn patients of anomalies. In the present case, the audible alarms were solely responsible for the timely identification of an intermittent, otherwise clinically nonreproducible, form of potentially fatal implantable cardioverter defibrillator system failure.
