Regina Plasmática Rápida (RPR):
Es una prueba diagnóstica rápida en laboratorios
Regina Plasmática Rápida (RPR): Es una prueba diagnóstica rápida en laboratorios de rutina, para indicar una posible infección por Treponema pallidum, agente causal de la sífilis. La RPR es una prueba NO ESPECIFICA, pues no detecta anticuerpos contra T. pallidum propiamente, sino que detecta anticuerpos contra sustancias liberadas por las células cuando son dañadas por la enfermedad (cardiolipina y lecitina). Existe otra prueba NO ESPECIFICA para la detección de sífilis, llamada VDRL (venereal Disease Research Laboratory test) con mucha atención y aplicación en muchos países del mundo. Tradicionalmente, la prueba serológica de sífilis se ha realizado utilizando pruebas no treponémicas (RPR o VDRL), sin embargo un resultados positivo debe confirmarse utilizando una prueba específica para T. pallidum como: FTA-ABS, siendo esta la prueba confirmatoria. #laboratory#laboratorioclinico#serology#inmunologia

. Tumors don't just develop overnight. They generally take years to grow, on average 7-10 years. . Did you know that cancer cells double every 90 days! When those cancer cells reach about 256 in number they will form their own vascular network completely separate and apart from the rest of the body, this is known as angiogenesis. . This new network of blood vessels is very foreign to the body and creates inflammation. This silent physiological process will continue until cancer cells reach into the billions and finally are large enough to be felt or seen with conventional methods. . A thermography screening detects inflammation in the body. Why wait 7-10 years until you have a tumor when you can have thermography screenings that detect inflammation and pathology sooner than later. . . . . . . . . . . . . . #angiogenesis#science#cancer#research#medicine#breastcancer#lab#eattobeatdisease#cancersurvivor#antiangiogenesis#cancerprevention#cancerresearch#healthylifestyle#restawhilerunamile#laboratory#avoidbypass#hypoxia#ilovescience#health#heart#alternativetherapy#microcirculation#biotechnology#holistichealing#eattoheal#inflammation#foodismedicine#holistic#healthiswealth#prevention

At this year’s annual NASA budget proposal, some of our student reporters got to take a closer look at a module from the International Space Station. This orbital laboratory is home to many crucial experiments such as “Veggie”, which focuses on growing plants in space. In addition to feeding Astronauts, this project has also helped farmers on Earth increase crop yield while reducing water usage. “Veggie” and many other projects are an important part of NASA’s #moon2mars program. .

This is a picture of me in Chicago during one of my residency interviews. I was fortunate because I was there on the second coldest day in Chicago history. So it’s kinda cool to be in a city during an “almost “ a record setting temperature. Last coldest day in Chicago was in 1985! . . The temperature today was -22F (-30C), with windchill -35F to -55F (-37C to - 48C). I had to alternate opening my R and L eye while walking because my eyes (the liquidy part) was freezing so quickly. So I walked around blinking around - luckily not many people were out... . . You maybe wondering why I was out walking around. I was getting deep dish pizza (aka pizza pie aka ThicC PiZzA) obv! . . . . . .⠀ .⠀ .⠀ .⠀ #neuropathology#coroner#postmortem#surgery#physician#bloody#neuropathology#student#medicine#health#stroke#science#medschool#Medicalschool#scrubs#housemusic#techno#morgue#medlife#histology#physicianassistant#science#laboratory#neurosciences#neurology#braintumor#oncology

shamelessly long selfie post: Today, like almost everyday, I was reminded why I love my job. One of my patients that I have known since I started at Texas Oncology as an MLT over a year ago, came in for a follow up for their cancer remission. My phlebotomist and I were so happy to see them; their hair had grown back and the color had come back to their face. It was like seeing an entirely different person. I told them how excited we were to see them happy and healthy. They then proceeded to tell my phlebotomist and I that they too, were happy to see us, and that we had made the chemotherapy experience much better with our positivism and how kind we had been to them through such a trying time. People have often asked me whether or not working in a 'cancer clinic' is hard. Not every day is easy, but if this place has taught me anything it is that even the smallest amount of optimism and compassion can make someone's journey better (especially your own). And for those of you that don't know, I have to be incredibly vague because of HIPAA (tldr; patient privacy is important).

This thermophilic microbe is happiest at temps of 85-95 degrees C in water, such as near hot springs or underwater volcanoes. . . In the opposite corner we have Deinococcus radiodurans! Like Aquifex aeolicus, it is an extremophile that is also one of the most radiation resistant organisms we know of. It even has the nickname "Conan the Bacterium" due to its hardiness. . .

Thought I’d start posting videos of some things I do in my lab, so here’s a little time lapse. I’m adding a certain compound (smells like shit) to plates of E. Coli (smells like literal shit). Cells that can mutate a certain gene will survive and grow, while everything else dies. Pretty much like a less exciting, bacteria version of The Hunger Games. It’s also kind of like forcing evolution to happen on a tiny scale. #molecularbiology#biology#laboratory#biochemistry#research#bacteria#microbes#microbiology#science#scientist

Durante os períodos de chuvas a saúde pode ficar comprometida. Calor, umidade e água são o cenário perfeito para a proliferação do mosquito Aedes aegypti, transmissor da Dengue. A transmissão se dá pela picada do mosquito infectado pelo vírus da doença. Febre alta, dores musculares intensas, dor ao movimentar os olhos, falta de apetite, dor de cabeça, manchas vermelhas no corpo e indisposição são os principais sintomas.

Distinguished Speaker #seminar with Zdenek Dohnalek, from Pacific Northwest Nati
Distinguished Speaker #seminar with Zdenek Dohnalek, from Pacific Northwest National #Laboratory. Dr. Dohnalek is deputy director of the Institute for Integrated Catalysis and senior chief scientist in the Fundamental and Computational Sciences Directorate. His talk, titled “Activation of H-H and C-H Bonds on Oxide Supported Single Pd Atoms,” will be delivered today at 4 p.m. in KEC 1003. A brief abstract and bio are below. Abstract: Single-atom catalysts (SACs) have recently attracted great attention due to their ultimate metal efficiency and the promise of novel properties. However, at the atomic level, little is known about their stability, interactions with the support, and mechanisms by which they operate. Recently the Fe3O4(001) #surface has been shown to stabilize single metal atoms to elevated temperatures, making it a promising support for model SAC studies. We have probed the reactions of hydrogen and methanol on supported single Pd atoms on Fe3O4(001) using a combination of atomically resolved imaging, surface-sensitive spectroscopies, temperature programmed reactions, and theoretical calculations. Using these methods, we have attained a detailed mechanistic understanding of elementary reaction steps and demonstrated that H2 cleaves heterolytically and H is spilled over onto Fe3O4(001). For methanol, we have shown that α-C-H bond can be activated already at room temperature to form formaldehyde. These studies compare and contrast #unique catalytic properties of the supported Pd atoms with those of Pd #nanoparticles. Biography: My #research centers on experimental studies of fundamental #model systems that are prerequisite for understanding complex processes that take place in heterogeneous catalysis. The chemistry of interest focuses on reactions that are critical for achieving a zero-carbon-footprint economy such as biomass conversion, photocatalytic #water splitting, and CO2 hydrogenation. The primary goal of the surface #science approach used in my lab is to achieve a detailed, site-specific, molecular level understanding of the kinetics and dynamics of elementary reaction steps on well-defined surfaces, supported #clusters and #single atoms.
