The aim of the present study was to determine whether age, gender, functional status, histology, tumor location, number of metastases, and levels of the tumor markers, lactate dehydrogenase (LDH) and albumin, are poor prognostic factors for the response to chemotherapy in patients with carcinoma of unknown primary site. A total of 149 patients diagnosed with carcinoma of unknown primary site that was histologically confirmed, and treated with chemotherapy in the Oncology Hospital, National Medical Center, 'Century XXI' IMSS, Mexico City, Mexico during the period between January 2002 to December 2009, were carefully selected for the present study...

The outcome of an Entamoeba histolytica infection is variable and the contribution of genetic diversity within E. histolytica to human disease is not fully understood. The information provided by the whole genome sequence of the E. histolytica reference laboratory strain (HM-1:IMSS) and thirteen additional laboratory strains have been made publically available. In this review theories on the source of the unexpected level of structural diversity found in E. histolytica will be discussed.

Drift tube-ion mobility spectrometers (DT-IMSs) are used to separate and characterize the structures of gas phase ions. Recent work in coupling an atmospheric pressure DT-IMS to a condensation particle counter (CPC) has extended the application of drift tube ion mobility spectrometry to nanoparticle analysis, with measurements possible for singly charged particles up to 20 nm in diameter. In examining systems with such large analytes, often of interest is not only separation, but also determination of the nanoparticle size or mobility distribution function, defined as the nanoparticle concentration per unit mobility/size...

The Código Infarto (Infarction Code) strategy is part of the comprehensive care program "A Todo Corazón" (To All Heart), whose aim is to reinforce the prevention and health care of cardiovascular diseases. Mexico faces a big challenge, since it is the country with greater mortality secondary to acute myocardial infarction (AMI) in the first 30 days in patients of 45 years or older (28% compared with 7.9% of the average). In addition, Mexico's population has a high prevalence of risk factors (hypertension, diabetes, tobacco use, dyslipidemias, overweight, and obesity)...

As part of its commitment to improve healthcare services persistently, the Instituto Mexicano del Seguro Social (IMSS) takes part in the constant training of its healthcare personnel, since the Institute knows that this has an impact on creating a virtuous circle of higher quality and giving cordial attention to patients. That is the reason why the Unidad de Educación, Investigación y Políticas en Salud has set up different programs, which offer diverse oportunities of study, always in line with the needs of the Institute...

BACKGROUND: Multiple sclerosis is a central nervous system demyelinating disease with unknown etiology. However, it is believed to be a multifactorial disease resulting from an interaction of genetic and environmental factors. Immigrant studies have been performed to provide a better view of the pattern of this interaction. We aimed to report the prevalence of MS Afghan immigrants of Isfahan, a population who share the same environment as Isfahan residents but with different genetic backgrounds...

An inter-comparison study was conducted to assess the capability of dosimetry systems of individual monitoring services (IMSs) in Gabon and Ghana to measure personal dose equivalent Hp(10) in photon fields. The performance indicators assessed were the lower limit of detection, linearity and uncertainty in measurement. Monthly and quarterly recording levels were proposed with corresponding values of 0.08 and 0.025 mSv, and 0.05 and 0.15 mSv for the TLD and OSL systems, respectively. The linearity dependence of the dosimetry systems was performed following the requirement given in the Standard IEC 62387 of the International Electrotechnical Commission (IEC)...

Cardiovascular diseases are a major public health problem because of their they impact on more than 30% of all deaths worldwide. In our country and in the Instituto Mexicano del Seguro Social (IMSS) are also the leading cause of death and the main cause of lost of healthy life years due to disability or premature death. 50% of deaths are premature; most of them are due to acute myocardial infarct. However, the investment for cardiovascular health is poor and there are no comprehensive cares programs focused on the treatment of this diseases or the control of their risk factors...

The early symptoms of tularemia and plague, which are caused by Francisella tularensis and Yersinia pestis infection, respectively, are common to other illnesses, resulting in a low index of suspicion among clinicians. Moreover, because these diseases can be treated only with antibiotics, rapid isolation of the bacteria and antibiotic susceptibility testing (AST) are preferable. Blood cultures of patients may serve as a source for bacteria isolation. However, due to the slow growth rates of F. tularensis and Y...

INTRODUCTION: The purpose of this study is to demonstrate the surgical technique for the correction of midfacial deformities; vertical excess and posteroanterior hypoplasia. This situation obligates the need to move the whole osseous structure in an oblique posteroanterior movement that should correct both midfacial deformities. This should also correct the lip incompetence while improving the malar projection on a profile view of the patient. We also present a mathematical formula that gives the angulation needed for moving the midface complex in a simultaneous vertical and posteroanterior direction...

It comprised a series of cases over a period of 4 years, held at the Hospital of Cardiology of the Centro Médico Nacional Siglo XXI, IMSS. From 2008 to 2011, admitted to Emergency 184 patients with suspected pulmonary embolism, of which 41 were removed; of the 143 remaining cases, only 127 patients was diagnosed with PE. The other 16 patients had other diagnoses. In 86% of patients showed electrocardiographic pattern S1Q3T3 and 39% had RBBB, in 17 (13.3%) patients there was hemodynamic instability, and in 94...

OBJECTIVE: To assess serum interleukin-6 (IL-6)level in patients with systemic sclerosis (SSc) and its correlations with European Scleroderma Study Group activity score (EUSTAR), Scleroderma Assessment Questionnaire (SAQ), disability index and cardiopulmonary involvement. METHODS: Twenty SSc patients and 10 matched healthy controls were included. Serum IL-6 was measured in patients and controls. Disease activity, status,and disability were assessed.Cardiopulmonary involvement was evaluated by pulmonary function tests (PFTs), six minute walk test, echocardiography, and high resolution computed tomography (HRCT) of chest...

In an endeavor to develop efficacious antiprotozoal agents 4-(7-chloroquinolin-4-yl) piperazin-1-yl)pyrrolidin-2-yl)methanone derivatives (5-14) were synthesized, characterized and biologically evaluated for antiprotozoal activity. The compounds were screened in vitro against the HM1: IMSS strain of Entamoeba histolytica and NF54 chloroquine-sensitive strain of Plasmodium falciparum. Among the synthesized compounds six exhibited promising antiamoebic activity with IC50 values (0.14-1.26μM) lower than the standard drug metronidazole (IC50 1...

BACKGROUND: Overweight and obesity in adolescence is a public health problem and a risk factor for chronic noncommunicable diseases. To prevent further diseases, preventive interventions are needed, including educational programmes, addressed in a primary care setting, that include the whole family.

BACKGROUND: Excretory-secretory (ES) proteins of E. histolytica are thought to play important roles in the host invasion, metabolism, and defence. Elucidation of the types and functions of E. histolytica ES proteins can further our understanding of the disease pathogenesis. Thus, the aim of this study is to use proteomics approach to better understand the complex ES proteins of the protozoa. METHODS: E. histolytica ES proteins were prepared by culturing the trophozoites in protein-free medium...

The reaction of E-2-ferrocenylmethylidenetetralones and E,E-2,6-bis-(ferrocenylmethylidene)-cyclohexanone with 2-aminothiophenol proceed with high diastereoselectivity, forming the ~4.5:1 mixture of trans- and cis-isomers of polycyclic ferrocenylthiazepines, respectively. The reactions of E,E-2,5-bis-(ferrocenylmethylidene)cyclopentanone and E,E-3,5-bis-(ferrocenylmethylidene)-1-methyl-4-piperidone with 2-aminothiophenol take place stereo specifically to form the diastereomeric tricyclic thiazepines of cis- and trans-configuration, respectively...
