Evolution and conservation of immunological activity
Vaz, N.M.;
Brazilian Journal of Medical and Biological Research , 2006, DOI: 10.1590/S0100-879X2006005000049
Abstract: paraphrasing what gregory bateson says on evolution, we might say that: "immunology has long been badly taught. in particular, students - and even professional immunologists - acquire theories of immunological activity without any deep understanding of what problems these theories attempt to solve."
Selective transport in systems with correlated disorder
Makarov, N.M.;
Revista mexicana de física , 2008,
Abstract: we analyze the recent results concerning the anomalous localization properties of one-dimensional and quasi-one-dimensional guiding structures with stratified and surface disorder. the main focus of our study is the role of long-range correlations in random scattering. it is shown that with a proper type of correlations, one can construct a stratification or surface profile that results in a complete transmission/reflection within a prescribed region of the wave number of incoming classical or quantum waves.
Study on Antimicrobial Resistant in Saudi Arabia
N.M. Abdalla
Research Journal of Medical Sciences , 2012, DOI: 10.3923/rjmsci.2011.94.98
Abstract: This study aimed at assessing the underlying causes of antimicrobial resistance in Saudi Arabia. About 50 patients randomly selected whose proved to have Staphylococcus antimicrobial resistance detected by Bact tech in Assir hospital microbiology laboratory. A special questionnaire was used to assess the knowledge, attitude and practice of patients towards using antimicrobials beside epidemiological and demographic data. Results showed that the nationality of all patients were Saudian (49 patients) only one was a Sudanese. About 22 patients were 16-40 years of age, the attitude of patients towards their treating doctor or pharmacist involved 13, deferent 11, critical (serious) 14 and ignored by 12 which almost equally distributed. About 64% patients used to exaggerate their symptoms to their doctor to let him prescribed any antimicrobial drugs. About 64% of patients purchase the antimicrobial drugs depending on the quality. Knowing the dosage of antimicrobial was enlisted by 84% patients. About 64% of patients used to have description of the antimicrobial dosage by treating physicians 20% by pharmacists. About 35 patients (70%) have received drug side effects description. The patients compliance grading <50% towards following their medication dosage was enlisted in 22 patients (44%). About 27 patients (54%) have no home animals while 23 patients (46%) have got home animals (7 patients have cats, 7 have goats, 6 have sheep, 2 have camels and 1 have dog). Only 7 patients (14%) have noticed infected wound on their home animals, 2 patients of them (4%) used to treat their home infected animals. About 20 patients (40%) used to through some of antimicrobial home waste in open carbidge. Conclusion deduced from of this study; antimicrobial resistance is a major health problem and patients often do not comply with antimicrobial prescription, enhancing the development of antimicrobial resistance during treatment.
Epidemiology of Infertility in Gezira Region, Central of Sudan
N.M. Abdalla
Research Journal of Medical Sciences , 2012, DOI: 10.3923/rjmsci.2011.56.60
Abstract: This study aimed at identifying the etiology of infertility among Sudanese couples. This study was a cohort study and it was held in Wad medani city, Gezira state (central of Sudan), the study group was composed of 200 infertile couples presented with infertility to the primary health care units. Demographic and epidemiological data were collected in special questionnaire. Medical history and examination was performed by the health centre doctor, midwife, nurse. Variable investigations were done including; blood, urine, hormonal assay, seminal analysis, histosalpingiography and ultra sounds. Outcome results were 79.5% were suffered from primary infertility and 20.5% had secondary infertility. Infertility due to husbands only was 20% that due to wives alone was 37.5% and infertility due to both couple was 31% while those with unknown aetiology was 11%. Sexual Transmitted Diseases (STDs) were not incriminated as an infertility etiological factor.
Heavy Metals Content of Crude Oil Sludge/Poultry Manure and Crude Oil Sludge/Municipal Solid Waste Composts
N.M. John
Agricultural Journal , 2013,
Abstract: Composting of crude Oil production Sludge (OS) differently with Poultry Manure (PM) and Municipal solid Waste (MW) was carried out at John Ker Nigeria Research Site in Ikot Ekpene, Akwa Ibom State, Nigeria, to evaluate the heavy metals content of the cured composts. Each of the two compost combinations (OSPM and OSMW) was homogenously mixed and stored in jute bags using various ratios of 1:1, 1:5, 1:10 and 1:20 volume-volume basis, respectively, for six weeks. The result reveals that the content of heavy metals in the fresh oily sludge and municipal solid waste was similar, but higher than that of fresh poultry manure. Mean contents of essential nutrients such as Zn, Cu Mn and Fe in the among OSPM cured composts were; 270.8, 24.1, 339.6 and 856.5 mg kg 1 compared to 286.4, 469.9, 219.73 and 851.0 mg kg 1 in the OSMW composts, respectively. There were low mean concentrations of heavy metals such as Vi(6.72), Ni(8.67), Pb(0.004) and Cd(0.001) in the OSPM cured composts, unlike Vi(4.4), Ni(8.2), Pb(61.1) and Cd(3.20) mg kg 1, in the OSMW cured composts. The composting process created a favourable condition for the microbial degradation of the oily sludge, with heavy metals content of the cured composts influenced by the contents of these elements their fresh organic samples used.

COMENTARIU LA ARTICOLUL GANGRENA POST-OPERATORIE PROGRESIV A PIELII (Mircea M. Constantinescu i Al.Vasiliu - Revista de Chirurgie 1940; 11-12/43: 747-762)
N.M. Constantinescu
Jurnalul de Chirurgie , 2012,
Abstract: Mircea M. Constantinescu a fost unul dintre cei mai buni chirurgi ie i i din coala de chirurgie a profesorului Iacob Iacobovici. Articolul pe care l-am ales pentru a-l comenta dup 72 de ani de la apari ie dovede te interesul deosebit acordat de autori pentru n elegerea i descifrarea mecanismelor de producere ale gangrenei post operatorii bacteriene sinergice progresive [1], complica ie redutabil i atunci ca i acum. Ast zi tim c sinergismul microbian ncepe prin dezvoltarea unui germene aerob, mare consumator de oxigen (a a cum este stafilococul auriu, dar pot fi i al i germeni aerobi), care permite dezvoltarea ulterioar a streptococului microaerofil sau chiar anaerob, responsabil de extensia progresiv datorit echipamentului de proteaze.Ceea ce ne diferen iaz pe noi ast zi de chirurgii romani ai primei jum t i a secolului trecut este mai buna n elegere a modului cum ac ioneaz agresorul microbian, a modului n care se dezvolt mecanismele de ap rare ale agresatului - deci ale pacientului - i nu n ultimul rand un armamentarium terapeutic mult mai eficace mpotriva agresorului i pentru sus inerea agresatului. Faptul c noi cunoa tem aportul” nefast al asocia iilor aero-anaerobe n progresiunea n pat de ulei” a infec iei necrozante a impus terapia prin excizii chirurgicale f r mil ”, pentru aerisirea” pl gii, asociat cu administrarea de antibiotice cu spectru larg, eventual cu oxigenoterapie hiperbar pentru blocarea i eliminarea agen ilor bacterieni. Agresatul -deci bolnavul - este ajutat printr-o reechilibrare energic volemic , electrolitic i proteic corectandu-i-se deficitele nutri ionale, hipoxia, dezechilibrele glicemice sau de alt natur . Oricum trebuie s remarc m c aceste infec ii agresive nu i-au spus ultimul cuvant. Literatura medical consemneaz n ultimii 20 de ani noi i noi por i de intrare: gangrene cutanate dup o simpl epiziotomie [2], dup liposuc ie n scop estetic [3,4]. Lipsa de tegument postexcizional dep e te adesea posibilit ile unei epiteliz ri spontane i necesit aplicarea de grefe de piele liber despicat [5].
