Attention deficits are a prominent aspect of cognitive dysfunction after mild traumatic brain injury (MTBI). Patients frequently complain of distractibility and difficulty attending to more than one thing at a time, and several neuropsychological studies have found evidence for a specific attention deficit without general neuropsychological impairment. The present study examined the nature of attentional disturbance after MTBI using an extended version of the 2 and 7 Test, which introduced two conditions reflecting patients' subjective complaints: the ability to perform with background 'noise', and while simultaneously attending to a secondary task. The dual task demands produced a significant slowing in processing speed for both the MTBI patients and control subjects. However, the relative decline in processing speed appeared much greater for the patients with MTBI, and they differed from control subjects only in this condition. The results are consistent with findings that patients with MTBI exhibit relatively subtle cognitive deficits which are apparent primarily under conditions which require effortful or controlled cognitive processing and exceed their available cognitive resources. Thus, the attentional deficits apparent during dual task demands may represent decreased cognitive, and perhaps neural, efficiency which reflects MTBI patients' subjective complaints and functional impairments.

Health screenings for women age 65 and older
You should visit your health care provider from time to time, even if you are healthy. The purpose of these visits is to:
- Screen for medical issues
- Assess your risk for future medical problems
- Encourage a healthy lifestyle
- Update vaccinations
- Help you get to know your provider in case of an illness
Information
Even if you feel fine, you should still see your provider for regular checkups. These visits can help you avoid problems in the future. For example, the only way to find out if you have high blood pressure is to have it checked regularly. High blood sugar and high cholesterol levels also may not have any symptoms in the early stages. A simple blood test can check for these conditions.
There are specific times when you should see your provider or receive specific health screenings. The US Preventive Services Task Force publishes a list of recommended screenings. Below are screening guidelines for women age 65 and older.
BLOOD PRESSURE SCREENING
Have your blood pressure checked at least once every year. Watch for blood pressure screenings in your area. Ask your provider if you can stop in to have your blood pressure checked. You can also check your blood pressure using the automated machines at local grocery stores and pharmacies.
Ask your doctor if you need your blood pressure checked more often if:
- You have diabetes, heart disease , kidney problems , or are overweight or have certain other health conditions
- You have a first-degree relative with high blood pressure
- You are Black
- Your blood pressure top number is from 120 to 129 mm Hg, or the bottom number is from 70 to 79 mm Hg
BREAST CANCER SCREENING
- Women may do a monthly breast self-exam. However, experts do not agree about the benefits of breast self-exams in finding breast cancer or saving lives. Talk to your provider about what is best for you.
- Your provider may do a clinical breast exam during your preventive exam. Experts do not agree on the benefit of a breast examination.
- Women up to age 75 should have a mammogram every 1 to 2 years, depending on their risk factors, to check for breast cancer.
- Experts do not agree on the benefits of having a mammogram for women age 75 and older. Some do not recommend having mammograms after this age. Others recommend mammography for women in good health. Talk to your provider about what is best for you.
CERVICAL CANCER SCREENING
After age 65, most women who have not been diagnosed with cervical cancer or precancer can stop having screening tests, as long as:
- They have had 3 consecutive negative Pap test results or 2 consecutive negative PAP and HPV tests results within 10 years
- The most recent test occurred within 5 years
CHOLESTEROL SCREENING
If your cholesterol level is normal, have it rechecked at least every 5 years.
You should have repeat testing sooner if:
- Changes occur in your lifestyle (including weight gain and diet)
- You have high cholesterol, diabetes, heart disease, kidney problems, or certain other health conditions
COLORECTAL CANCER SCREENING
Until age 75, you should have screening for colorectal cancer on a regular basis. If you are age 76 or older, you should ask your doctor if you should receive screening. Several tests are available for colorectal cancer screening:
- A stool-based fecal occult blood (gFOBT) or fecal immunochemical test ( FIT ) every year
- A stool sDNA-FIT test every 1 to 3 years
- Flexible sigmoidoscopy every 5 years or every 10 years with stool testing with FIT done every year
- CT colonography ( virtual colonoscopy ) every 5 years
- Colonoscopy every 10 years
You may need a colonoscopy more often if you have risk factors for colon cancer, including:
- Ulcerative colitis
- A personal or family history of colorectal cancer
- A history of growths in your colon called adenomatous polyps
DENTAL EXAM
- Go to the dentist once or twice every year for an exam and cleaning. Your dentist will evaluate if you have a need for more frequent visits.
DIABETES SCREENING
You should be screened for diabetes every 3 years.
You may be tested more often If you have other risk factors for diabetes, such as:
- A first degree relative with diabetes
- You are overweight or have obesity, high blood pressure, prediabetes, or a history of heart disease
- Have an eye exam every 1 to 2 years. Your provider may recommend more frequent eye exams if you have vision problems or glaucoma risk.
- Have an eye exam that includes an examination of your retina (back of your eye) at least every year if you have diabetes.
HEARING TEST
- Have your hearing tested if you have symptoms of hearing loss .
IMMUNIZATIONS
Commonly needed vaccines include:
- Flu shot : get one every year
- Pneumococcal vaccines : you should receive this vaccine
- Tetanus-diphtheria and acellular pertussis (Tdap) vaccine : have as one of your tetanus-diphtheria vaccines if you did not receive it as an adolescent
- Tetanus-diphtheria : have a booster (or Tdap) every 10 years
INFECTIOUS DISEASE SCREENING
Screening for hepatitis C:
- All adults ages 18 to 79 should get a one-time test for hepatitis C .
Screening for human immunodeficiency virus (HIV):
- All people ages 15 to 65 should get a one-time test for HIV
Depending on your lifestyle and medical history, you may need to be screened for infections such as syphilis, chlamydia, and other infections.
LUNG CANCER SCREENING
You should have an annual screening for lung cancer with low-dose computed tomography (LDCT) if:
- You are age 50 to 80 years AND
- You have a 20 pack-year smoking history AND
- You currently smoke or have quit within the past 15 years
OSTEOPOROSIS SCREENING
- All women age 65 or older should have a bone density test (DEXA scan).
- Ask your provider which exercises or other interventions can help prevent osteoporosis or bone fractures.
PHYSICAL EXAMS
All adults should visit their provider from time to time, even if they are healthy. The purpose of these visits is to:
- Screen for diseases
- Assess risk of future medical problems
- Maintain a relationship with a provider in case of an illness
During the exam, your provider will ask questions about:
- Depression and anxiety
- Diet and exercise including exercises to improve your balance and reduce your risk of falling
- Alcohol and tobacco use
- Safety, such as use of seat belts and smoke detectors and intimate partner violence
- Whether you have had any falls or are afraid of falling
- Your medicines and risk for interactions
- Your provider may check your skin for signs of skin cancer , especially if you're at high risk.
- People at high risk include those who have had skin cancer before, have close relatives with skin cancer, or have a weakened immune system.

Two-pore domain potassium channels (K 2P ): Introduction

INTRODUCTION TO K 2P CHANNELS

Figure 1. Classification of function of two-pore domain channels. A. A phylogenetic tree calculated to show the relatedness of the 15 K 2P subunits found in humans based on ClustalW alignments of the IUPHAR accession numbers for each clone, (see http://www.guidetopharmacology.org/GRAC/IonChannelListForward?class=VGIC ). To date, functional expression has not been observed for K 2P 7, K 2P 12 and K 2P 15 (grey text). B. K 2P subunits are integral membrane proteins with internal amino (N) and carboxy (C) termini, four transmembrane domains (M1-M4) and two pore forming (P)-loops. C. Two K 2P subunits create a single, central K + selective conduction pore. One subunit is shown in green and a second in blue. Under physiological conditions, K + flow (red arrow) down a concentration gradient from the intra- to the extracellular milieu. D. Example whole-cell current from K 2P 1 channels heterologously expressed in CHO-K1 cells and studied with a deSUMOylating enzyme in the recording pipette. In both case, the inside of the cell contains 140 mM KCl. Left, The external solution contains 4 mM KCl. Right, The same cell recorded with 140 mM KCl on both sides of the membrane. E. Mean current-voltage relationships for Chinese hamster ovary (CHO-K1) cells expressing SENP1 activated K 2P 1 channels (adapted from [ 101 ]). Active K 2P 1 channels show openly rectifying (GHK) behavior. Under quasi-physiologic conditions (Δ, 4 mM external KCl) the channels pass more outward current but show a linear current-voltage relationship with symmetrical 140 mM KCl (▲).

K 2P CHANNELS AT ATOMIC RESOLUTION

Figure 2. The primary structures of the subunits of the voltage-gated sodium channels. A. Ribbon representations of the x-ray structure of human K 2P 4 resolved at 2.75 Å [ 18 ]. Left, The channel is viewed from the membrane plane with one subunit in red and the other in blue, K + ions are green, and the boundary of the membrane is in grey. Right, A view of the channel rotated by ~45° to show architecture wherein the outer pore helix interacts with the inner helix from the other subunit rather than its own. Dashed lines suggest loop regions that were not resolved. The ~35 Å cap domain above the outer mouth of the pore that bifurcates the entrance to the K + conduction pathway and the c-helix are indicated with arrows. B. A cross section of a surface view of human K 2P 10 colored by hydrophobicity where green is the most hydrophobic and blue is the least hydrophobic, [ 39 ]. The structure was solved to 3.9 Å in complex with norfluoxetine bound within both bilateral intramembrane side portals. Norfluoxetine is shown in light blue, dark blue, red, and orange for carbon, nitrogen, oxygen, and fluorine atoms, respectively. Click image for full size.
