Marine ecosystems worldwide are threatened by aquatic pollution; however, there is a paucity in data from the Caribbean region. As such, five heavy metals (arsenic, cadmium, copper, zinc, mercury) were measured in tissues of the scleractinian corals Porites furcata and Agaricia tenuifolia and in adjacent sediments in the Bocas del Toro Archipelago, Panama. Samples were collected from five reef ...

We compared the structural, biochemical, and physiological characteristics involved in photorespiration of intergeneric hybrids differing in genome constitution (DtDtR, DtDtRR, and DtRR) between the C3-C4 intermediate species Diplotaxis tenuifolia (DtDt) and the C3 species radish (Raphanus sativus; RR). The bundle sheath (BS) cells in D. tenuifolia included many centripetally located chloroplas...

We sought to determine the prevalence of hepatitis B virus (HBV) lamivudine (LAM)-resistant minority variants in subjects who once received LAM but had discontinued it prior to virus sampling. We performed direct PCR Sanger sequencing and ultradeep pyrosequencing (UDPS) of HBV reverse transcriptase (RT) of plasma viruses from 45 LAM-naive subjects and 46 LAM-experienced subjects who had discont...

Background: Lymphangioleiomyomatosis (LAM) is a progressive lungs disease that affects women at reproductive years. Sirolimus inhibits mammalian target of rapamycin (mTOR) and its administration in past studies was hopeful in treatment of patients with LAM. The aim of this study was to evaluate sirolimus therapy on lung function in LAM patients. Methods: We conducted a trial to evaluate the ef...

Lipoarabinomannan (LAM) is a component of the mycobacterial surface which has been associated with a variety of deleterious effects on immune system function. Despite the importance of LAM to the pathogenesis of mycobacterial infection, there is no information available on its fate in vivo. In this study, we determined the pharmacokinetics and tissue distribution of exogenously administered LAM...

We studied the cognitive improving and cerebral protective constituents in the roots of Polygala tenuifolia Willdenow, a well-known Chinese traditional medicine prescribed for amnesia, neurasthenia, palpitation, noctural emission and insomnia. Tenuifoliside B (1), which is one of the acylated oligosaccharides in the roots of P. tenuifolia, showed the cerebral protective effect on potassium cyan...

Lymphangioleiomyomatosis (LAM) is a progressive disorder of unknown etiology that predominantly affects the lungs, and the resulting respiratory failure can be fatal. Extrapulmonary LAM is a rare disease that often occurs concurrently with pulmonary LAM. Usually, extrapulmonary LAM presents as a localized, well-circumscribed mass. Due to the rare occurrence of extrapulmonary LAM and its atypica...

Background: Achillea tenuifolia Lam. (Compositae) with small yellow flowers and several times pinnately divided leaves in worm shape is known for many years in the folk medicine. It has been used to reduce sweating and to stop bleeding. It helps regulation of the menstrual cycle and reduces heavy bleeding and pain. Materials and Methods: Plant material (flower, leaf and stem) was collected in...

A 3 × 2 factorial experiment was conducted to investigate the effects of different ratios of dietary laminarin (LAM) and fucoidan (FUC) on growth performance and nutrient digestibility in newly weaned piglets. At weaning, 168 piglets (24 d of age; 6.8 kg live weight) were assigned to 1 of 6 dietary treatments (n = 14/treatment): (i) basal diet, (ii) basal diet + 240 mg/kg FUC, (iii) basal diet ...
