Clinically Relevant Dosage Of Vancomycin Does Not Negatively Impact Periosteum Derived Osteoblast Precursor Cellular Functions, Alexis Hernandez

Surgical site infections (SSI) can develop post-operatively and carry significant clinical and financial implications. SSI can carry a cost of up to $30,000 per case, as well as an estimated 6 day longer hospitalization. Patients with Type II Diabetes (DM) have an increased susceptibility to infection and suffer from poor bone healing overall. Therefore, diabetic patients who have undergone orthopedic surgery risk both an increased chance of developing an SSI as well as suboptimal bone healing. Vancomycin and other antibiotics have traditionally been used prophylactically to prevent infection, however the effect of vancomycin on bone healing in a diabetic population …

Vanadium Compounds Modulate Osteoblast Proliferation And Function, Bryan Sosa

Osteoblastogenesis is an essential part of the bone healing process. Insulin has been shown to improve bone healing in both normal and diabetic bone healing models. In addition, insulin mimetic compounds such as Zinc chloride (ZnCl2) and Vanadyl acetylacetonate (VAC) have also been shown to improve bone healing in these models as well. The purpose of this study was to determine the effects of vanadium compounds VAC and Vanadium (II) sulfate (VSO4) in osteoblast proliferation and function. In addition the mechanisms by which growth and function are facilitated by these Vanadium compounds were also evaluated. In …

Rna Interference Targeting Glucose-Regulated-Protein 78 Induces Hepg2 Cell Apoptosis, Brittany Blackman

Cancer is a complex genetic disease that is driven by genetic mutations resulting in chronic, inappropriate cell proliferation. Many current cancer therapies lack specificity towards tumor tissues, ultimately leading to adverse side effects and limited clinical efficacy. Recently, selective cancer cell therapy has examined a well-characterized cell surface marker that is preferentially expressed on tumor cells. The over-expression of an endoplasmic reticulum chaperone protein, 78-kDa glucose-regulated-protein (GRP78), has been observed on the surface of cancer cells, but not on normal tissues. By selectively targeting GRP78 with short-interfering RNA (siRNA), potent GRP78 silencing is anticipated by the RNA interference (RNAi) pathway. …

Localization And Binding Characteristics Of Kaposi's Sarcoma-Associated Herpesvirus Bcl-2 Protein In The Prevention Of Apoptosis, Erin T. St.Angelo

Kaposi's sarcoma-associated herpesvirus (KSHV) is the causative agent of various diseases, and it encodes a Bcl-2 homolog, KS-Bcl-2. The Bcl-2 family is important in regulating cellular apoptosis. Pro-apoptotic Bcl-2 family members promote apoptosis through mitochondrial pore formation by Bak and Bax, or through BH3 only domain activators and sensitizers. Anti-apoptotic members, such as cellular Bcl-2 prevent apoptosis through interactions with pro-apoptotic proteins, for instance inhibiting pore formation by binding to Bak and/or Bax. Even though, KS-Bcl-2 has been shown to have an anti-apoptotic function like its homolog, it does not bind to either Bak or Bax, and little is known …

Lipopolysaccharide (LPS) is a potent inflammagen that has been found to be primarily responsible for many symptoms caused by gram-negative bacterial infections. The LPS-initiated signal transduction pathways involve several terminal kinases, mainly p42/44 mitogen-activated protein kinase (MAPK), p38 MAPK and c-Jun N-terminal kinase (JNK), ultimately leading to increased expression of genes encoding such inflammatory cytokines as interleukin (IL )-1 �. IL-6 and tumor necrosis factors (TNF)-u. In this study, the effects of age on LPS-induced activation of MAPKs in the liver of rats were examined. Results show that the basal level of phosphorylated p42/44 MAPK was increased in postnatal day …

A dUTPase is a crucial enzyme that hydrolyzes dUTP to dUMP. This reaction prevents the mutagenic or lethal misincorporation of uracil into DNA. For that reason, the enzyme is required for efficient DNA replication. Previous studies have shown that has ORFl l dUTPase-like motifs and thus may be a dUTPase. Generally, gammaherpesviruses contain six characteristic dUTPase motifs. In particular ORFl 1 and contains motifs 1, 2, 4, 6. While the characteristic motifs of gamroaberpesviruses include motifs 1, 2, 3, 4, 5, and 6, the number of dUTPase-like motifs in ORFl 1 's protein sequence is substantial. Thus, ORFl 1 may …

Prolonged exposure to morphine down-regulates mu opioid receptors (MOR) on both undifferentiated and differentiated (retinoic acid or phorbol ester treated) SHSY-5Y cells. However, morphine pretreatment does not alter MOR receptor affinity for morphine. To investigate the molecular basis for MOR regulation after exposure to its selective agonists, we have developed a quantitative competitive reverse transcriptase-polymerase chain reaction (QC-RT PCR) to quantify the expression of MOR in SHSY-SY cells. Differentiation of SHSY-5Y cells with retinoic acid or phorbol ester up regulated MOR mRNA expression by 30 % and 78%, respectively. A 24 hours treatment with morphine (10 µM) down regulated MOR …

Seizures cause selective neuronal cell loss in vulnerable regions such as the hippocampus, cortex, thalamus or substantia nigra (SN) in human or experimental animals. While the HF can propagate seizures, the SN pars reticulata (SNR) regulates the spread ol seizures in an age-dependent fashion, and the pars compacta (SNC) affects extrapyramidal motor control. In mature animals, both structures are wlnerable to seizure-induced damage. In prepubescent rats, seizure susceptibility is reduced and CA 1 region rs primarily affected. The proto-oncogenes, Bcl-2 and Bax, encode specific proteins that inhibit and promote programmed cell death, respectively. In order to determine whether proto-oncogenes are …

Antiphospholipid Syndrome (APS) is an evolving autoimmune disease with numerous clinical manifestations. APS occurs in two forms: Primary Antiphospholipid Syndrome (PAPS) and secondarily in association with other autoimmune disorders such as Systemic Lupus Erythematosis (SLE). In the brief period since its discovery as a cofactor for anticardiolipin antibodies, p1-glycoprotein I (�GPI; apolipoprotein H) has been recognized as the autoantigen in the absence of anionic phospholipid when appropriately presented to human autoantibodies. Recent studies suggest that this presentation requires the surface-dependent unmasking of a cryptic epitope. Immunoassays of autoantibodies directed against p1GPI, developed through the application of suitable polymeric matrices, may …
