enhanced protein translation underlies improved metabolic and physical adaptations to different exercise training modes in young and old humans
robinson et al. 2017
•High-intensity interval training improved age-related decline in muscle mitochondria •Training adaptations occurred with increased gene transcripts and ribosome proteins •Changes to RNA with training had little overlap with corresponding protein abundance •Enhanced ribosomal abundance and protein synthesis explain gains in mitochondria
The molecular transducers of benefits from different exercise modalities remain incompletely defined. Here we report that 12 weeks of high-intensity aerobic interval (HIIT), resistance (RT), and combined exercise training enhanced insulin sensitivity and lean mass, but only HIIT and combined training improved aerobic capacity and skeletal muscle mitochondrial respiration. HIIT revealed a more robust increase in gene transcripts than other exercise modalities, particularly in older adults, although little overlap with corresponding individual protein abundance was noted. HIIT reversed many age-related differences in the proteome, particularly of mitochondrial proteins in concert with increased mitochondrial protein synthesis. Both RT and HIIT enhanced proteins involved in translational machinery irrespective of age. Only small changes of methylation of DNA promoter regions were observed. We provide evidence for predominant exercise regulation at the translational level, enhancing translational capacity and proteome abundance to explain phenotypic gains in muscle mitochondrial function and hypertrophy in all ages.

rarely have coughing caused by own nasal mucus anymore, because have learned to swallow it before it reaches the lungs.
simple muscle tension experiment: if place flat of palm of hand against conductive bone near ear, or on ear, at night, while head rests gently on palm — pillow useful for placement. if tense either muscles in arm or cheek, can hear the subtle vibrations as muscles act in dynamic tension, lack of vibration when all muscles relaxed.
can't promise that you'll never have a sore throat ever again, but I can promise that this will reduce the severity of the symptoms. Sore throats commonly occur when we are ill, and the symptom is a pain in the throat area. The pain comes because the upper airway, just below the epiglottis, has become drier, and the lining of the airway thus becomes more sensitive. Causes of the dryness could include illness slowing mucus production deeper in the lungs, or very dry air in the house or outside. The temporary solution, however, is easy — you can often relieve a painful sore throat in minutes — all you need to do is to swallow. Swallowing, without actually needing to swallow any food or water, is sufficient to encourage local mucus movement and production right where it is needed most. You may want to experiment with swallowing at different intervals or in different patterns.
Swallowing eases the symptom of a sore throat by encouraging wetter mucous from lungs to move faster towards the normal exit point of the oesophagus. Thus the dried out area of the trachea or throat which is hurting is covered by mucous and soothed temporarily.
Seems like common sense once you know it but seems slightly esoteric before you understand why it works
For a longer–term solution, drink water often enough to replenish your internal supplies so you can produce enough mucus to suit the air or illness. The only downside is that you'll no longer be able to complain about having a sore throat when you are ill, so people won't believe your illness is as bad as theirs!
prevent dry–air nosebleeds
wait for new thin film of wet mucous to form between dried mucous and nasal passage before attempting to blow out dried mucous from nose. if this means stifling sneezes for a little while, do so.
investigating the case of human nose shape and climate adaptation

The evolutionary reasons for variation in nose shape across human populations have been subject to continuing debate. An import function of the nose and nasal cavity is to condition inspired air before it reaches the lower respiratory tract. For this reason, it is thought the observed differences in nose shape among populations are not simply the result of genetic drift, but may be adaptations to climate. To address the question of whether local adaptation to climate is responsible for nose shape divergence across populations, we use Qst–Fst comparisons to show that nares width and alar base width are more differentiated across populations than expected under genetic drift alone. To test whether this differentiation is due to climate adaptation, we compared the spatial distribution of these variables with the global distribution of temperature, absolute humidity, and relative humidity. We find that width of the nares is correlated with temperature and absolute humidity, but not with relative humidity. We conclude that some aspects of nose shape may indeed have been driven by local adaptation to climate. However, we think that this is a simplified explanation of a very complex evolutionary history, which possibly also involved other non-neutral forces such as sexual selection.
The study of human adaptation is essential to our understanding of disease etiology. Evolutionary investigations into why certain disease phenotypes such as sickle-cell anemia and lactose intolerance occur at different rates in different populations have led to a better understanding of the genetic and environmental risk factors involved. Similarly, research into the geographical distribution of skin pigmentation continues to yield important clues regarding risk of vitamin D deficiency and skin cancer. Here, we investigate whether variation in the shape of the external nose across populations has been driven by regional differences in climate. We find that variation in both nares width and alar base width appear to have experienced accelerated divergence across human populations. We also find that the geospatial distribution of nares width is correlated with temperature, and absolute humidity, but not with relative humidity. Our results support the claim that local adaptation to climate may have had a role in the evolution of nose shape differences across human populations.
sneezing causing split lips
if you sneeze suddenly when your lips are very dry, such as after a long night in a dry room, you may split your lips. to prevent this, try to wet your lips before you sneeze.
nose blocked with mucous
first blow as much out as you can, then try to drain by tilting head back and breathing in through nose as much as you can. after a while it will clear. this works by allowing the nose to clear and dry out.
