Alias: LAM Note: Lymphangioleiomyomatosis (LAM) is a multisystem disease, affecting predominantly premenopausal women, that is characterized by proliferation of abnormal smooth muscle-like cells (LAM cells) leading to the formation of lung cysts, fluid-filled cystic tumors in the axial lymphatics (e.g., lymphangioleiomyomas), and abdominal tumors, primarily in the kidneys, comprising adipose ce...
BACKGROUND Detection of lipoarabinomannan (LAM), a Mycobacterium tuberculosis (Mtb) cell wall antigen, is a potentially attractive diagnostic. However, the LAM-ELISA assay has demonstrated variable sensitivity in diagnosing TB in diverse clinical populations. We therefore explored pathogen and host factors potentially impacting LAM detection. METHODS LAM-ELISA assay testing, sputum smear and ...
ion and function application employ the notion of substitution. Recall the inference rule and its representation in LF: e1 ↪→ lam x. e1 e2 ↪→ v2 [v2/x]e1 ↪→ v ev app e1 e2 ↪→ v ev app : ΠE1:exp. ΠE2:exp. ΠE′ 1:exp→ exp. ΠV2:exp. ΠV :exp. eval E1 (lam E′ 1) → eval E2 V2 → eval (E′ 1 V2) V → eval (app E1 E2) V. As before, we transcribe this (and the trivial rule for evaluating λ-expressions) into...
Lymphangioleiomyomatosis (LAM) is a rare cystic lung disease presenting with cough, dyspnea on exertion and recurrent pneumothorax. Substantial achievements have been made during the past two decades regarding the pathogenesis, diagnosis and management of this disorder. LAM, affecting almost exclusively women, is associated with inactivating tuberous sclerosis complex (TSC) gene mutations in LA...
Lymphangioleiomyomatosis (LAM) is a rare disease in women. Patients with LAM develop metastatic smooth-muscle cell adenomas within the lungs, resulting in reduced pulmonary function. LAM cells contain mutations in tuberous sclerosis genes (TSC1 or TSC2), leading to up-regulation of mTORC1 activity and elevated proliferation. The origin of LAM cells remains unknown; however, inactivation of Tsc2...
BACKGROUND In Zimbabwe, sputum smear microscopy (SSM) is the routinely used TB diagnostic tool in hospitalised HIV-infected patients. However, SSM has poor sensitivity in HIV-infected patients. We compared performance of urine lipoarabinomannan strip test (LAM) and SSM among hospitalized HIV-infected patients with suspected TB. METHODS Hospitalized HIV-infected patients with suspected TB were...
Maintenance of cell-wall integrity in Mycobacterium tuberculosis is essential and is the target of several antitubercular drugs. For example, ethambutol targets arabinogalactan and lipoarabinomannan (LAM) biosynthesis through the inhibition of several arabinofuranosyltransferases. Apart from their role in cell-wall integrity, mycobacterial LAMs also exhibit important immunomodulatory activities...
Lipomannan (LM) and lipoarabinomannan (LAM) are mycobacterial glycolipids containing a long mannose polymer. While they are implicated in immune modulations, the significance of LM and LAM as structural components of the mycobacterial cell wall remains unknown. We have previously reported that a branch-forming mannosyltransferase plays a critical role in controlling the sizes of LM and LAM and ...
44 The efficacy of entecavir (ETV) in chronic hepatitis B (CHB) patients who were 45 exposed to lamivudine (LAM), but had no detectable LAM-resistance (LAM-R) is not 46 well evaluated. In this study, we aimed to evaluate whether the probability of 47 developing genotypic resistance to ETV in LAM-exposed patients with/without LAM-R 48 is comparable to that in antiviral-naïve patients. This retro...
The use of titanium and its alloys has increased in various industries recently, because of their superior properties of these alloys. Titanium alloys are generally classified as difficult to machine materials because of their thermo-mechanical properties such as high strength-to-weight ratio and low thermal conductivity. Laser Assisted Machining (LAM) improves the machinability of high strengt...
