Makna kata Jihad dalam pendekatan semantika Al Qur’an

Pada zaman modern ini, persoalan keagamaan semakin beragam dan terus berkembang di masyarakat. Salah satu di antara persoalan tersebut adalah kasus-kasus intoleransi dan ekstrimisme yang semakin banyak bermunculan. Di antara factor yang melatarbelakangi hal tersebut adalah kesalahpahaman dalam memaknai kata Jihad. Kesalahpahaman ini berujung kepada aksi-aksi ekstrimisme yang membahayakan umat beragama. Belakangan pun ramai diperbincangkan, ketika sekelompok orang menyuarakan ajakan jihad dalam adzan. Perlu adanya kajian ulang untuk memahami kata jihad yang terdapat dalam al-Qur’an. Dalam hal ini, pendekatan semantika al-Qur’an akan menjadi pisau analisis yang dapat memunculkan makna jihad secara komperehnsif. Tujuan dari penelitian ini adalah untuk mengetahui bagaimana makna jihad dalam al Qur’an ditinjau oleh pendekatan semantika al-Qur’an. Penelitian ini menggunakan metode penelitian kualitatif dengan jenis data kualitatif. data primer dalam penelitian ini adalah ayat-ayat Al-Qur’an yang terdapat kata jihad. Selain itu, kajian semantik dalam buku Relasi Tuhan dan Manusia: Pendekatan Semantik terhadap Al-Quran karya Toshihiko Izutsu. penulis menggunakan beberapa referensi mengenai kajian seputar jihad dan semantik. Pengumpulan data yang digunakan dalam penelitian ini adalah studi kepustakaan atau Library Research dengan metode pembahasan deskriptif-analisis. Analisis data yang dilakukan oleh penulis dalam penelitian kali ini menggunakan metode Induksi. Hasil dari penelitian ini adalah makna dasar dari kata jihad yang terdapat dalam alQur’an memiliki makna berperang dan bersungguh-sungguh. Kemudian makna relasional yang terdapat dalam periode Qur’anik memiliki keterkaitan dengan empat kata, yaitu: (1) Jalan Allah (Fi> sabi>lillah); (2) harta dan jiwa (amwa>l dan anfus); (3) kaum kafir dan kaum munafik (al-kuffa>r dan al-muna>fiqu>n); dan (4) keimanan (ayma>nihim).Medan semantik dari kata jihad merujuk kepada tiga hal, yaitu: (1) tujuan jihad; (2) objek jihad; dan (3) jenis jihad. Welthanschauung kata jihad dapat kita munculkan dua hal, yaitu: kewajiban dalam Islam dan sebuah kesungguhan. Dua hal tersebut, nantinya dapat dikembangkan sehingga dapat memunculkan konsep baru tentang jihad di setiap masa yang berbeda

Serological and molecular characterization of Cryptosporidium species from humans in Sokoto State, Nigeria

Cryptosporidium species are one of the most common causes of gastrointestinal infection in humans around the world. This study aimed at the characterization of Cryptosporidium species in humans using the 18S rRNA gene. Among the 368 human faecal samples screened using Cryptosporidium antigen Copro-ELISA kit, 61 (16.6%) were positive. The positive faecal samples were subjected to Nested PCR for the amplification of 830 bp fragments of small subunit (SSU) rRNA gene and followed by nucleotide sequencing. Out of the 61 copro-ELISA positive samples, 5 (8.2%) were PCR positive for Cryptosporidium species (3 (4.9%) of C. parvum and 2 (3.3%) of C. hominis). Two HIV patients were found to be harbouring C. parvum and C. hominis, so also as hypertensive and diarrheic patients harbouring C. parvum and C. hominis, respectively. Higher prevalence rates of Cryptosporidium was found in young children (11.1%), males (8.7%), loose faeces (42.9%) than older age groups (8.7%), females (7.9%) and well-formed (3.1%) or mucoid/pasty faeces (0%) based on the data gathered from the close-ended questionnaire also used on each human subject. This study was the first to report C. parvum and C. hominis infecting humans in Sokoto state, Northwestern Nigeria. It is suggested that a multi-locus study of Cryptosporidium species in developing countries would be necessary to determine the extent of transmission of Cryptosporidium in the populations

Dark matter scenarios in the minimal SUSY B-L model

We perform a study of the dark matter candidates of a constrained version of the minimal R-parity-conserving supersymmetric model with a gauged $U(1)_{B-L}$. It turns out that there are four additional candidates for dark matter in comparison to the MSSM: two kinds of neutralino, which either correspond to the gaugino of the $U(1)_{B-L}$ or to a fermionic bilepton, as well as "right-handed" CP-even and -odd sneutrinos. The correct dark matter relic density of the neutralinos can be obtained due to different mechanisms including new co-annihilation regions and resonances. The large additional Yukawa couplings required to break the $U(1)_{B-L}$ radiatively often lead to large annihilation cross sections for the sneutrinos. The correct treatment of gauge kinetic mixing is crucial to the success of some scenarios. All candidates are consistent with the exclusion limits of Xenon100.Comment: 45 pages, 22 figures; v2: extended discussion of direct detection cross section, matches published versio

Pre-hospital ECG for acute coronary syndrome in urban India: A cost-effectiveness analysis

<p>Abstract</p> <p>Background</p> <p>Patients with acute coronary syndrome (ACS) in India have increased pre-hospital delay and low rates of thrombolytic reperfusion. Use of ECG could reduce pre-hospital delay among patients who first present to a general practitioner (GP). We assessed whether performing ECG on patients with acute chest pain would improve long-term outcomes and be cost-effective.</p> <p>Methods</p> <p>We created a Markov model of urban Indian patients presenting to a GP with acute chest pain to compare a GP's performing an ECG versus not performing one. Variables describing the accuracy of a GP's referral decision in chest pain and ACS, ACS treatment patterns, the effectiveness of thrombolytic reperfusion, and costs were derived from Indian data where available and other developed world studies. The model was used to estimate the incremental cost-effectiveness ratio (ICER) of the intervention in 2007 US dollars per quality adjusted life years (QALY) gained.</p> <p>Results</p> <p>Under baseline assumptions, the ECG strategy cost an additional $12.65 per QALY gained compared to no ECG. Sensitivity analyses around the cost of the ECG, cost of thrombolytic, and referral accuracy of the GP yielded ICERs for the ECG strategy ranging between cost-saving and$1124/QALY. All results indicated the intervention is cost-effective under current World Health Organization recommendations.</p> <p>Conclusions</p> <p>While direct presentation to the hospital with acute chest pain is preferable, in urban Indian patients presenting first to a GP, an ECG performed by the GP is a cost-effective strategy to reduce disability and mortality. This strategy should be clinically studied and considered until improved emergency transport services are available.</p

Dynamics of biofilm formation and the interaction between Candida albicans and methicillin-susceptible (MSSA) and -resistant Staphylococcus aureus (MRSA)

Polymicrobial biofilms are an understudied and a clinically relevant problem. This study evaluates the interaction between C. albicans, and methicillin- susceptible (MSSA) and resistant (MRSA) S. aureus growing in single- and dual-species biofilms. Single and dual species adhesion (90 min) and biofilms (12, 24, and 48 h) were evaluated by complementary methods: counting colony-forming units (CFU mL-1), XTT-reduction, and crystal violet staining (CV). The secretion of hydrolytic enzymes by the 48 h biofilms was also evaluated using fluorimetric kits. Scanning electron microscopy (SEM) was used to assess biofilm structure. The results from quantification assays were compared using two-way ANOVAs with Tukey post-hoc tests, while data from enzymatic activities were analyzed by one-way Welch-ANOVA followed by Games-Howell post hoc test ( = 0.05). C. albicans, MSSA and MRSA were able to adhere and to form biofilm in both single or mixed cultures. In general, all microorganisms in both growth conditions showed a gradual increase in the number of cells and metabolic activity over time, reaching peak values between 12 h and 48 h (<0.05). C. albicans single- and dual-biofilms had significantly higher total biomass values (<0.05) than single biofilms of bacteria. Except for single MRSA biofilms, all microorganisms in both growth conditions secreted proteinase and phospholipase-C. SEM images revealed extensive adherence of bacteria to hyphal elements of C. albicans. C. albicans, MSSA, and MRSA can co-exist in biofilms without antagonism and in an apparent synergistic effect, with bacteria cells preferentially associated to C. albicans hyphal forms.CNPq (Council for Technical and Scientific Development) (Grant 400658/2012-7)Fundação para a Ciência e Tecnologia (FCT), Portugal (SFRH/BPD/71076/2010)CAPES(Coordination for the Improvement of Higher Level Personnel

The Persistent Circulation of Enterovirus 71 in People's Republic of China: Causing Emerging Nationwide Epidemics Since 2008

Emerging epidemics of hand-foot-and-mouth disease (HFMD) associated with enterovirus 71 (EV71) has become a serious concern in mainland China. It caused 126 and 353 fatalities in 2008 and 2009, respectively. The epidemiologic and pathogenic data of the outbreak collected from national laboratory network and notifiable disease surveillance system. To understand the virological evolution of this emerging outbreak, 326 VP1 gene sequences of EV71 detected in China from 1987 to 2009 were collected for genetic analyses. Evidence from both traditional and molecular epidemiology confirmed that the recent HFMD outbreak was an emerging one caused by EV71 of subgenotype C4. This emerging HFMD outbreak is associated with EV71 of subgenotype C4, circulating persistently in mainland China since 1998, but not attributed to the importation of new genotype. Originating from 1992, subgenotype C4 has been the predominant genotype since 1998 in mainland China, with an evolutionary rate of 4.6∼4.8×10−3 nucleotide substitutions/site/year. The phylogenetic analysis revealed that the majority of the virus during this epidemic was the most recent descendant of subgenotype C4 (clade C4a). It suggests that the evolution might be one of the potential reasons for this native virus to cause the emerging outbreak in China. However, strong negative selective pressure on VP1 protein of EV71 suggested that immune escape might not be the evolving strategy of EV71, predicting a light future for vaccine development. Nonetheless, long-term antigenic and genetic surveillance is still necessary for further understanding
