Accelerated mammary gland development in intellectually disabled.

Answers

Answer 1

Answer:

The vitamin D receptor (VDR) is present in mammary gland, and VDR ablation is associated with accelerated glandular development during puberty. VDR is a nuclear receptor whose ligand, 1,25-dihydroxyvitamin D [1,25-(OH)(2)D] is generated after metabolic activation of vitamin D by specific vitamin D hydroxylases. In these studies, we demonstrate that both the VDR and the vitamin D 1-alpha hydroxylase (CYP27B1), which produces 1,25-(OH)(2)D are present in mammary gland and dynamically regulated during pregnancy, lactation, and involution. Furthermore, we show that mice lacking VDR exhibit accelerated lobuloalveolar development and premature casein expression during pregnancy and delayed postlactational involution compared with mice with functional VDR. The delay in mammary gland regression after weaning of VDR knockout mice is associated with impaired apoptosis as demonstrated by reductions in terminal deoxynucleotidyl transferase-mediated deoxyuridine nick-end labeling staining, caspase-3 activation and Bax induction. Under the conditions used in this study, VDR ablation was not associated with hypocalcemia, suggesting that altered mammary gland development in the absence of the VDR is not related to disturbances in calcium homeostasis. Furthermore, in the setting of normocalcemia, VDR ablation does not affect milk protein or calcium content. These studies suggest that the VDR contributes to mammary cell turnover during the reproductive cycle, and its effects may be mediated via both endocrine and autocrine signaling pathways. Unlike many mammary regulatory factors that exert transient, stage-specific effects, VDR signaling impacts on mammary gland biology during all phases of the reproductive cycle.

Use trigonometric identities to verify each expression is equal. csc2(x) - 2csc(x)cot(x) + cot2(x) = tan2(x/2)

Answers

By definition of csc and cot,

csc²(x) - 2 csc(x) cot(x) + cot²(x) = …

… = 1/sin²(x) - 2 cos(x) / sin²(x) + cos²(x) / sin²(x)

Combining fractions,

… = (1 - 2 cos(x) + cos²(x)) / sin²(x)

Factorize the numerator and use the Pythagorean identity,

cos²(x) + sin²(x) = 1,

to rewrite the denominator.

… = (1 - cos(x))² / (1 - cos²(x))

Cancel a factor of 1 - cos(x).

… = (1 - cos(x)) / (1 + cos(x))

Using the half-angle identities,

sin²(x) = (1 - cos(2x))/2

cos²(x) = (1 + cos(2x))/2

it follows that

1 - cos(x) = 2 sin²(x/2)

1 + cos(x) = 2 cos²(x/2)

and so

… = (2 sin²(x/2)) / (2 cos²(x/2))

… = sin²(x/2) / cos²(x/2)

Finally, by definition of tangent,

… = tan²(x/2)

List the angles of ∆ abc from smallest to largest. Ab = 20, bc = 12, ca = 10.

Answers

The angle of the triangle ABC from smallest to largest are approximately 22°, 27° and 131°.

The sides of the triangle are as follows;

AB = 20

BC = 12

AC = 10

Let's find ∠A using cosine rule,

a² = b² + c² - 2bc cos A

cos A = b² + c² - a² / 2bc

Therefore,

cos A = 10² + 20² - 12²  / 2 × 10 × 20

cos A = 100 + 400 - 144 / 400

cos A = 356 / 400

cos A = 0.89

A = cos⁻¹ 0.89

A = 27.1267531173

∠A ≈ 27°

Using sine rule let's find ∠B

12 / sin 27 = 10 / sin B

cross multiply

12 sin B = 10 sin 27

sin B = 10 sin 27 / 12

sin B = 10 × 0.45399049974  / 12

sin B = 4.5399049974  / 12

B = sin⁻¹ 0.37832541645

B = 22.2299936087

∠B = 22°

Using sum of triangle theorem let's find ∠C

∠C = 180 - 27 - 22

∠C = 131°

The angles from smallest to largest are approximately 22°, 27° and 131°.

Answers

Answer:

Given

Rate of interest = 10% per annum

Principal for the first year = Rs 6000

Interest for the first year = Rs (6000 × 10 × 1) / 100

= Rs 600

Amount at the end of first year = Rs 6000 + Rs 600

= Rs 6600

Principal for the second year = Rs 6600

Interest for the second year = Rs (6600 × 10 × 1) / 100

= Rs 660

Amount for the second year = Rs 6600 + Rs 660

= Rs 7260

Therefore, compound interest for 2 years = final amount – (original) Principal

= Rs 7260 – Rs 6000

We get,

= Rs 1260

Pauline chasse has just signed a lease agreement with landlord, wayne godbrey to rent a house he owns in delano. The lease states definite beginning (january 1, 2016) and ending (october 30, 2016) dates, and sets forth the rent amount and due dates and all additional property and personal information required in such a lease. Wayne hands a copy to pauline, but she notices that he has not signed it. When she comments about this to him, he tells her that signatures are not necessary since the lease is for less than a year. Which of the following is true of this situation?.

Answers

The correct option that is true as regards Wayne's situation about the lease is;

B; Leases of less than one year are not required to be in writing. However, if a lease IS in writing, then it must be signed by the lessor (in this case, Wayne).

The missing options are;

Under the Statute of Frauds in California,

A) leases of less than one year are not even required to be in writing, and therefore, signatures are not required.

B) Leases of less than one year are not required to be in writing. However, if a lease IS in writing, then it must be signed by the lessor (in this case, Wayne).

C) Leases of less than one year are not required to be in writing; but if there is a written lease, then it must be signed by both the lessee and lessor.

D) Because the property being leased is located in Northern California, a lease agreement is required to be both written and signed by the lessor if the lease period is for 6 months or more

Now, California has some principles that guide the regulation of the real estate industry and according to the California Principles of Real State, it has to be said that leases of less than one year are not required to be in writing.

Now, even though the law stated that the consent of both parties are not enough to bind themselves in the lease agreement, it is recommended that just for the sake of keeping things legally binding as regards the agreement between both parties, then both parties may state it in written and the lessor must sign it.

Coordinates are two numbers (Cartesian coordinates) or a letter and a number that point to a specific point on a grid known as a coordinate plane. A coordinate plane has four quadrants and two axes: x (horizontal) and y (vertical).

The horizontal and vertical distances from the two reference axes are used to describe the position of a point on a coordinate plane.

X and its values on the x coordinate represented the smaller integer. y and its values on the y coordinate represented the greater integer. The larger number is three times the smaller number. This implies that

y = 3x

Also, the larger number is the sum of the smaller and larger numbers. This implies that y = x + 4
