One highly economical type of regulation controls the synthesis of 3 enzymes at the genetic transcription or translation level (see the section on the molecular basis of bacterial genetics (p 160mg malegra fxt plus otc. Growth and Culturing of Bacteria Nutrients The term bacterial culture refers to proliferation of bacteria with a suitable nutrient substrate quality malegra fxt plus 160mg. Other necessities include sources of carbon and nitrogen for synthesis of specific bacterial compounds as well as minerals such as sul- fur, phosphorus, calcium, magnesium, and trace elements as enzyme activa- tors. Nutrient agar liquefies when heated to 1008C and does not return to the gel state until cooled to 458C. Selective mediums Contain inhibitor substances that allow only certain bacteria to proliferate. The Physiology of Metabolism and Growth in Bacteria 165 Growth and Cell Death Bacteria reproduce asexually by means of simple transverse binary fission. The time required for a reproduction cycle (G) is called the generation time (g) and can vary greatly from species to species. Fast-growing bacteria cultivated in vitro have a gen- eration time of 15–30 minutes. Obligate anaerobes grow much more slowly than aerobes; this is true in vitro as well. Of course the generation time also depends on the nutrient con- tent of the medium. The so-called normal growth curve for bacteria is obtained by inoculat- ing a nutrient broth with bacteria the metabolism of which is initially quies- cent, counting them at intervals and entering the results in a semilog coor- dinate system (Fig. The lag phase (A) is characterized by an increase in bacterial mass per unit of volume, but no increase in cell count. During this phase, the metabolism of the bacteria adapts to the conditions of the nutrient medium. In the following log (or exponential) phase (C), the cell count in- creases logarithmically up to about 109/ml. This is followed by growth decel- eration and transition to the stationary phase (E) due to exhaustion of the nutrients and the increasing concentration of toxic metabolites. The generation time can only be determined dur- ing phase C, either graphically or by determining the cell count (n) at two different times and applying the formula: t2 À t1 g ¼ : log2 n2 À log2 n1 Normal Growth Curve of a Bacterial Culture Fig. F A B (Hours) Time (Days) Kayser, Medical Microbiology © 2005 Thieme All rights reserved.
Worksheet 3-11 My Reﬂections If you get stuck on any of these exercises quality malegra fxt plus 160 mg, or if you see more advantages than disadvantages to your change-blocking beliefs malegra fxt plus 160 mg with visa, consider talking with your therapist or possibly a close friend for further help and advice. Looking Out for Self-Sabotage Overcoming anxiety or depression is tough and sometimes even frightening work. Self-sabotage describes the things you do to keep from addressing and cor- recting your problems, and it appears in various forms and disguises. Chapter 3: Overcoming Obstacles to Change 39 Complete the checklist in Worksheet 3-12 to see if you’re falling into the self-sabotage trap. I want to wait to make changes until just the right time, but that time never comes. It isn’t hard to see how thoughts like these could bog you down and prevent active efforts to change. Yet almost everyone engages in at least a little self-sabotage, whether consciously or not. Don’t make your problems worse by pummeling yourself when you see that you’re self- sabotaging. When you feel them getting in your way, ﬁght back and argue against them using the Self-Sabotage Diary presented in the next section. Stopping self-sabotage Throughout this book, we ask you to write out your thoughts, feelings, beliefs, and life events. That’s because writing is an invaluable tool for battling problematic emotions, sorting out issues, achieving important insight, and solving problems. In this section, we invite you to track and record your inevitable acts and thoughts of self-sabotage in a diary. None of her col- leagues are aware that she suffers from considerable anxiety and depression. She worries that others will discover that she doesn’t deserve her professional success. She realizes that, for the last decade, she has neglected friends and family in pursuit of success. Now, she feels lonely and despondent; success hasn’t brought her the happiness she expected, and her anxiety and depression have only increased.
Hypnotic – pertaining to sleep or hypnosis order malegra fxt plus 160mg without prescription, an agent which induces sleep or which dulls the senses generic malegra fxt plus 160 mg, drugs which cause insensibility to pain by inhibiting afferent impulses or the central centers of the brain receiving sensory impressions, and thus causing partial or complete unconsciousness Hypochondriac – affected with a morbid interest in health and disease Hypoglycemia – deficiency of sugar in the blood, a condition in which there is a level less than 80, hyper function of the pancreas may cause it or injection of an excessive amount of insulin Hypokalemia – an abnormally low concentration of potassium in the blood Hypokinesia – decreased motor reactions to stimulus Hypomania – hypomania and excitement, with a moderate change in behavior Hyponatremia – a decreased concentration of sodium (salt) in the blood Hypophysis – the pituitary body or gland Hypotension – decrease of systolic and diastolic blood pressure below normal, deficiency in tone or tension, below a blood pressure of 90/50 is pathologic, if increased pressure is followed by decreased pressure can be a serious condition, if the systolic and the diastolic drops proportionately – the patient will respond to the administration of stimulants, hypotension causes an accumulation of blood in the veins and slows down the arterial current Hypothalamic – a portion of the diencephalons compromising the ventral wall of the third ventricle below the hypothalamic sulcus, source of the hormones vasopressin and oxytocin stored and released by the neural lobe of the hypophysis Hypothermia – having a body temperature below normal, an art of lowered body temperature, usually between 78 - 90 degrees, to reduce oxygen need during surgery (especially cardiovascular and neurological procedures) and in hypoxia, to reduce blood pressure and to remedy Hypothyroid – marked by insufficient thyroid secretions in the body resulting in diminished basal metabolism, intolerance of cold temperatures, fatigue, mental apathy, physical sluggishness, constipation, muscle aches, dry skin and hair, and coarsening of features. These symptoms are called myxedema 416 Hypotonia – reduced tension, relaxation of arteries, loss of tone of the muscles or intra-ocular pressure Hypoventilation – reduced rate and depth of breathing Hypovolemia– diminished blood supply Hypoxemia – decreased oxygen tension (concentration) in arterial blood, measured by arterial oxygen partial pressure (PaO2) values. Symptoms may include memory issues, balance, ambulation, depending which area of the brain is affected Infiltrates – to pass into or through a substance or a space. A shadow seen on a chest xray, and assumed to represent blood, pus, or other body fluids in the lung Influenza – an acute contagious respiratory infection marked by fevers, muscle aches, headaches, prostration, cough, and sore throat. The disease usually strikes during the winter Influx – a flowing in 417 Insomnia – chronic inability to sleep or sleep prematurely ended or interrupted by periods of wakefulness, may be caused by a heavy late meal, with some coffee or other stimulants, including sugar in any form, overtiredness, mental fatigue, worry, excitement, and principally the fear of being unable to sleep Interstitial – placed or lying between; pertaining to interstices or spaces within an organ or tissue Intestinal atony – lack of muscle tone in the intestine and failure to contract normally, causing a delay in movement of fecal debris to exit the intestine Intracellular – within the cell Intracerebral – within the cerebellum of the brain. It consists of two lateral hemispheres and a narrow middle portion called the vermis. The cerebellum is involved in synergic control of skeletal muscles and plays an important role in the coordination of voluntary movements. It receives afferent impulses but is not a reflex center in the usual sense; however, it may reinforce some reflexes and inhibit others. Although the cerebellum does not initiate movements, it interrelates with many brainstem structures in executing various movements, including maintaining proper posture and balance; walking and running; fine involuntary movements as required in writing, dressing, eating, and playing musical instruments; and smooth tracking movements of the eyes. The cerebellum controls the property of movement such as speed, acceleration, and trajectory Intra ocular pressure – pressure with in the eyeball Intrathecal – within the spinal canal; within a sheath Involutional - a rolling or turning inward – associated with senile, pre-senile types, and manic-depressive groups Iritis – inflammation of the iris of the eye associated with pain, lacrimation, photophobia, diminution of vision, the iris appears swollen, dull and muddy, and pupil is contracted, irregular and sluggish in reaction Irritable bowel – the way the bowel responds excessively to a stimulus – diarrhea may be increased Ischemia – a temporary deficiency of blood flow to any organ or tissue. The deficiency may be caused by diminished blood flow either through a regional artery or throughout the circulation 418 J Jaundice – a condition characterized by yellowness of the skin, white of eyes, mucous membranes and body fluids, due to deposition of bile pigments resulting from excess bilirubin in the blood, it may result from obstruction of bile passageways, excessive destruction of red blood cells, or disturbances in functioning of the liver cells K Keratitis – inflammation and ulceration of the cornea, which is usually associated with decreased visual acuity, Eye pain, tearing, and light sensitivity are the most common symptoms Ketogenic diet – diet is high in fat, adequate in protein, and has negligible amounts of carbohydrate. It was created to stimulate some of the metabolic effects of fasting, a state known to decrease seizures in some individuals. They seem to do well for 2 or 3 months, then the seizures begin to start in again. Ketones – normal metabolic products, B-hydroxylbutyric acid and aminoacetic acid, from which acetone may arise spontaneously. The two acids are products of lipid pyruvate metabolism, and are oxidized by the muscles.
