Abstract
INTRODUCTION Following twenty years of economic and social growth, Liberia's fourteen-year civil war destroyed its health system, with most of the health workforce leaving the country. Following the inauguration of the Sirleaf administration in 2006, the Ministry of Health & Social Welfare (MOHSW) has focused on rebuilding, with an emphasis on increasing the size and capacity of its human resources for health (HRH). Given resource constraints and the high maternal and neonatal mortality rates, MOHSW concentrated on its largest cadre of health workers: nurses. CASE DESCRIPTION Based on results from a post-war rapid assessment of health workers, facilities and community access, MOHSW developed the Emergency Human Resources (HR) Plan for 2007-2011. MOHSW established a central HR Unit and county-level HR officers and prioritized nursing cadres in order to quickly increase workforce numbers, improve equitable distribution of workers and enhance performance. Strategies included increasing and standardizing salaries to attract workers and prevent outflow to the private sector; mobilizing donor funds to improve management capacity and fund incentive packages in order to retain staff in hard to reach areas; reopening training institutions and providing scholarships to increase the pool of available workers. DISCUSSION AND EVALUATION MOHSW has increased the total number of clinical health workers from 1396 in 1998 to 4653 in 2010, 3394 of which are nurses and midwives. From 2006 to 2010, the number of nurses has more than doubled. Certified midwives and nurse aides also increased by 28% and 31% respectively. In 2010, the percentage of the clinical workforce made up by nurses and nurse aides increased to 73%. While the nursing cadre numbers are strong and demonstrate significant improvement since the creation of the Emergency HR Plan, equitable distribution, retention and performance management continue to be challenges. CONCLUSION This paper illustrates the process, successes, ongoing challenges and current strategies Liberia has used to increase and improve HRH since 2006, particularly the nursing workforce. The methods used here and lessons learned might be applied in other similar settings.

Abstract
A randomized controlled trial of four interventions was conducted using tubewells (n=2,486), liquid sodium hypochlorite ('Clorin') distributed with an improved water vessel (n=2,305), hygiene promotion (n=1,877), and a combination of the three (n=2,040) to create an evidence-base for water policy in Afghanistan. A fifth group served as a control (n=2,377). Interventions were randomized across 32 villages in Wardak province. Outcomes were measured through two household surveys separated by one year and twice-weekly household surveillance conducted over 16 months. The households receiving all three interventions showed reduction in diarrhoea compared with the control group, through both longitudinal surveillance data (IRR [95% CI]=0.61 [0.47-0.81]) and cross-sectional survey data (AOR [95% CI]=0.53 [0.30-0.93]). This reduction was significant when all household members were included, but did not reach significance when only children under five were considered. These results suggest multi-barrier methods are necessary where there are many opportunities for water contamination. Surveillance data suggested a greater impact of interventions on reducing diarrhoeal diseases than data from the surveys. Higher economic status as measured through household assets was associated with lower rates of diarrhoea and greater intervention uptake, excepting Clorin. Use of soap was also associated with lower prevalence of diarrhoea.

Abstract
Establishment of intestinal infection with Entamoeba histolytica depends on the mouse strain; C57BL/6 mice are highly resistant, and C3H/HeJ mice are relatively susceptible. We found that resistance to intestinal infection was independent of lymphocyte activity or H-2 haplotype and occurred in the first hours to days postchallenge according to in vivo imaging. At 18 h postchallenge, the ceca of resistant C57BL/6 mice were histologically unremarkable, in contrast to the severe inflammation observed in susceptible C3H/HeJ mice. Comparison of cecal gene expression in C3H/HeJ and C57BL/6 mice demonstrated that there was parasite-induced upregulation of proinflammatory and neutrophil chemotaxis transcripts and there was downregulation of transforming growth factor beta signaling molecules. Pretreatment with dexamethasone abrogated the partial resistance of C3H/HeJ or CBA mice through an innate, lymphocyte-independent mechanism, but it had no effect on the high-level resistance of C57BL/6 mice. Similarly, administration of a neutrophil-depleting anti-Gr-1 monoclonal antibody (RB6-8C5) decreased the partial resistance of CBA mice and led to severe pathology compared to control antibody-treated mice, but it had no effect on C57BL/6 resistance. These data indicate that there are discrete mechanisms of innate resistance to E. histolytica depending on the host background and, in contrast to other reports, imply that neutrophils are protective and not damaging in intestinal amebiasis.

Abstract
Anodic fluorination of N-benzoyl, N-acethyl-, and N-formylthiazolidine derived from L-cysteine was carried out in dimethoxyethane (DME) and acetonitrile containing various supporting fluoride salts using an undivided cell. Highly regioselective fluorination proceeded to provide the corresponding 5-monofluorinated thiazolidine derivatives in good yields in DME, and the diastereoselectivitiy was moderate to high regardless of the supporting fluoride salts. The diastereoselectivitiy of the fluorination was greatly affected by the bulkyness of the subsitituent on the nitrogen atom, and N-benzoylthiazolidine gave much higher diastereoselectivity compared with N-formyl derivative. The fluorination of the thiazolidines was not achieved by commercially available fluorinating reagents such as N-fluoropyridinium salts.

Abstract
The objective of this study was to compare the safety and efficacy of maintenance tocolysis with oral diltiazem to oral nifedipine in achieving 37 weeks gestation. After successful intravenous tocolysis with magnesium sulfate, 69 women with preterm labor at <35 weeks gestation were randomly assigned to nifedipine (20 mg orally every 4-6 hr), or diltiazem (30-60 mg orally every 4-6 hr). The primary outcome was the percentage of patients achieving 37 weeks gestation. Maternal cardiovascular alterations and neonatal outcomes were also assessed. Sixty-nine patients were available for final analysis. Less patients on diltiazem as compared to nifedipine achieved 37 weeks (15.1% vs. 41.7%, P = 0.019). Gestational age at delivery was also less for patients receiving diltiazem (35.5 +/- 3.5 weeks vs. 33.4 +/- 3.9 weeks, P = 0.022). There were fewer days gained in utero from randomization to delivery with diltiazem as compared to nifedipine; however, this difference was not statistically significant (22.4 +/- 16.3 days vs. 31.2 +/- 24.4 days, P = 0.084). Maternal blood pressure and pulse during tocolysis did not differ significantly between groups. Despite the theoretical advantages of diltiazem tocolysis, maintenance tocolysis with diltiazem offered no benefit over nifedipine in achieving 37 weeks gestation. The cardiovascular alterations with either drug in normotensive, pregnant patients appear minimal.
